1 On September 2, 2025, Vietnam commemorated the 80th anniversary of its National Day with a
2 parade so spectacular that it could hardly be compared with any event in the region. At Ba Đình
3 Square, more than 16,000 soldiers marched proudly, accompanied by helicopters and aircrafts
4 roaring overhead. Leaders emphasized that the event not only honored history but also
5 demonstrated the nation’s commitment to peace and innovation.
6 Foreign delegations from China, Russia, Laos, and Cambodia joined, highlighted Vietnam’s growing
7 role across Asia. Meanwhile, the government announced that it would provide the one-time financial
8 supports to every citizen, a gesture welcomed across society. The amnesty program also released
9 thousands of prisoners, many of whom had behaved well during their sentences, including 66
10 foreigns.
11 At the same time, Hanoi introduced the A80 digital platform, designed to act as an indispensable
12 “smart company” for the celebrations. The platform offered real-time updates, interactive maps, and
13 livestreams, ensuring that no visitor was left in the dark. However, some users complained that the
14 app crashed too frequently on the launch day, though improvements were implemented immediately.
15 More than the technological tool, A80 symbolized Vietnam’s determination to merge traditions with
16 modernity, reminding citizens and foreign friends alike that the nation’s journey is as much about
17 looking backward with pride as looking forward to confidence

Social media, as a dynamic platform for online interaction, have become integral to modern society.
Defined as interactive Web 2.0 applications, social media thrives on generated-user content, including text,
images, and videos. Accessible through both web-based and mobile applications, social media encourages the
sharing and co-creation of content, contributing to the formation of digital communities. These platforms serve
various purposes, including documentary of memories, information sharing, self-promotion, and relationship
building. The early 2000s witnessed the rapid proliferation of social media platforms, with notably services such
as Friendster, Myspace, Facebook, YouTube, and Twitter gaining widespread popularity. By 2015, social
networks made up the significant portion of the world's online activity, accounting up approximately 22% of the
global online time, a trend fueled in part by the widespread adoption of smartphones. As of January 2023, the
global population of social media user has surged to 4.76 billion, constitute nearly 60% of the world's total

Part 4. Read the following passage and do the tasks that follow.
SOSUS: Listening to the Ocean
A
The oceans of Earth cover more than 70 percent of the planet’s surface, yet, until quite recently, we knew less
about their depths than we did about the surface of the Moon. Distant as it is, the Moon has been far more
accessible to study because astronomers long have been able to look at its surface, first with the naked eye and
then with the telescope-both instruments that focus light. And, with telescopes tuned to different wavelengths of
light, modern astronomers can not only analyze Earth’s atmosphere but also determine the temperature and
composition of the Sun or other stars many hundreds of light-years away. Until the twentieth century, however, no
analogous instruments were available for the study of Earth’s oceans: Light, which can travel trillions of miles
through the vast vacuum of space, cannot penetrate very far in seawater.
B
Curious investigators long have been fascinated by sound and the way it travels in water. As early as 1490,
Leonardo da Vinci observed: “If you cause your ship to stop and place the head of a long tube in the water and
place the outer extremity to your ear, you will hear ships at a great distance from you.” In 1687, the first
mathematical theory of sound propagation was published by Sir Isaac Newton in his Philosophiae Naturalis
Principia Mathematica. Investigators were measuring the speed of sound in the air beginning in the mid-
seventeenth century, but it was not until 1826 that Daniel Colladon, a Swiss physicist, and Charles Sturm, a French
mathematician, accurately measured its speed in the water. Using a long tube to listen underwater (as da Vinci
had suggested), they recorded how fast the sound of a submerged bell traveled across Lake Geneva. Their result-
1,435 meters (1,569 yards) per second in the water of 1.8 degrees Celsius (35 degrees Fahrenheit) – was only 3
meters per second off from the speed accepted today. What these investigators demonstrated was that water –
whether fresh or salt – is an excellent medium for sound, transmitting it almost five times faster than its speed in
air.
C
In 1877 and 1878, the British scientist John William Strutt, third Baron Rayleigh, published his two-volume seminal
work, The Theory of Sound, often regarded as marking the beginning of the modern study of acoustics. The
recipient of the Nobel Prize for Physics in 1904 for his successful isolation of the element argon, Lord Rayleigh
made key discoveries in the fields of acoustics and optics that are critical to the theory of wave propagation in
fluids. Among other things, Lord Rayleigh was the first to describe a sound wave as a mathematical equation (the
basis of all theoretical work on acoustics) and the first to describe how small particles in the atmosphere scatter
certain wavelengths of sunlight, a principle that also applies to the behavior of sound waves in water.
D
A number of factors influence how far sound travels underwater and how long it lasts. For one, particles in seawater
can reflect, scatter, and absorb certain frequencies of sound – just as certain wavelengths of light may be reflected,
scattered, and absorbed by specific types of particles in the atmosphere. Seawater absorbs 30 times the amount
of sound absorbed by distilled water, with specific chemicals (such as magnesium sulfate and boric acid) damping
out certain frequencies of sound. Researchers also learned that low-frequency sounds, whose long wavelengths
generally pass over tiny particles, tend to travel farther without loss through absorption or scattering. Further work
on the effects of salinity, temperature, and pressure on the speed of sound has yielded fascinating insights into
the structure of the ocean. Speaking generally, the ocean is divided into horizontal layers in which sound speed is
influenced more greatly by temperature in the upper regions and by pressure in the lower depths. At the surface
is a sun-warmed upper layer, the actual temperature and thickness of which varies with the season. At mid-
latitudes, this layer tends to be isothermal, that is, the temperature tends to be uniform throughout the layer
because the water is well mixed by the action of waves, winds, and convection currents; a sound signal moving
down through this layer tends to travel at an almost constant speed. Next comes a transitional layer called the
thermocline, in which temperature drops steadily with depth; as the temperature falls, so does the speed of sound.
E
The U.S. Navy was quick to appreciate the usefulness of low-frequency sound and the deep sound channel in
extending the range at which it could detect submarines. In great secrecy during the 1950s, the U.S. Navy launched
a project that went by the code name Jezebel; it would later come to be known as the Sound Surveillance System
(SOSUS). The system involved arrays of underwater microphones, called hydrophones, that were placed on the
ocean bottom and connected by cables to onshore processing centers. With SOSUS deployed in both deep and
shallow water along both coasts of North America and the British West Indies, the U.S. Navy not only could detect
submarines in much of the northern hemisphere, it also could distinguish how many propellers a submarine had,
whether it was conventional or nuclear, and sometimes even the class of sub.
F
The realization that SOSUS could be used to listen to whales also was made by Christopher Clark, a biological
acoustician at Cornell University, when he first visited a SOSUS station in 1992. When Clark looked at the graphic
representations of sound, scrolling 24 hours a day, every day, he saw the voice patterns of blue, finback, minke,
and humpback whales. He also could hear the sounds. Using a SOSUS receiver in the West Indies, he could hear
whales that were 1,770 kilometers (1,100 miles) away. Whales are the biggest of Earth’s creatures. The blue
whale, for example, can be 100 feet long and weigh as many tons. Yet these animals also are remarkably elusive.
Researchers studying whales firsthand must wait in their ships for the animals to surface. A few whales have been
tracked briefly in the wild this way but not for very great distances, and much about them remains unknown. Using
the SOSUS stations, scientists can track the whales in real-time and position them on a map. Moreover, they can
track not just one whale at a time, but many creatures simultaneously throughout the North Atlantic and the eastern
North Pacific. They also can learn to distinguish whale calls. For example, Fox and colleagues have detected
changes in the calls of finback whales during different seasons and have found that blue whales in different regions
of the Pacific Ocean have different calls.
G
SOSUS, with its vast reach, also has proved instrumental in obtaining information crucial to our understanding of
Earth’s weather and climate. Specifically, the system has enabled researchers to begin making ocean temperature
measurements on a global scale – measurements that are keys to puzzling out the workings of heat transfer
between the ocean and the atmosphere. The ocean plays an enormous role in determining air temperature – the
heat capacity in only the upper few meters of the ocean is thought to be equal to all of the heat in the entire
atmosphere. For sound waves traveling horizontally in the ocean, speed is largely a function of temperature. Thus,
the travel time of a wave of sound between two points is a sensitive indicator of the average temperature along its
path. Transmitting sound in numerous directions through the deep sound channel can give scientists
measurements spanning vast areas of the globe. Thousands of sound paths in the ocean could be pieced together
into a map of global ocean temperatures and, by repeating measurements along the same paths overtimes,
scientists could track changes in temperature over months or years.
H
Researchers also are using other acoustic techniques to monitor climate. Oceanographer Jeff Nystuen at the
University of Washington, for example, has explored the use of sound to measure rainfall over the ocean.
Monitoring changing global rainfall patterns undoubtedly will contribute to understanding major climate change as
well as the weather phenomenon known as El Niño. Since 1985, Nystuen has used hydrophones to listen to rain
over the ocean, acoustically measuring not only the rainfall rate but also the rainfall type, from drizzle to
thunderstorms. By using the sound of rain underwater as a “natural” rain gauge, the measurement of rainfall over
the oceans will become available to climatologists.

Part 5: Read the article about being a film and television drama extra, identify which section A–D each of
the following is mentioned. For questions 41-50, Write ONE letter A–D in the corresponding numbered
space provided. Each letter may be used more than once.
A. During a break in the filming of a TV drama, I gravitated towards the table laden with hot coffee and biscuits.
As I reached it, however, I was duly informed that is was reserved for the “talent” – the real actors – and was
directed towards a rickety table, on which sat an urn of hot water, some sugar packets, and nothing else. I tell this
tale, not just to grumble, but because it sums up the stark divide between the cast and the little people in the
background. Referring to us on set by our technical name of “supporting artistes” is meant to make us feel more
important, I suppose. “Walking background” and “human props” are common, faintly humorous labels for us, but
they’re fitting. Extras aren’t supposed to say anything during a take; we aren’t paid to talk. Nor are we allowed to
talk between takes when everything is being reset. A gentle murmur of conversation will inevitably well up among
some groups, at which point one of the assistant directors will immediately bellow for silence.
B. There are other non-negotiables, and failing to obey them could result in you being fired and blacklisted
from the industry. Your contract specifically orders you not to talk to any of the actors. On one production, I was
introduced to the lead actor and told what my role would be in that particular scene. I smiled at him in a mild attempt
at camaraderie and he started right through me. Then, the expression on the face of the lead actress made it clear
she had decided not to make an effort with me. I knew I was only an extra, but they might have at least feigned
some interest. So why go through this? Well, when I first signed up, I, like many others I know, saw it as an
interesting way of earning a second income. The far from generous fees, however, soon meant I regarded it as
little more than a hobby, and had I had a family, I probably wouldn’t have been able to do it.
C. Occasionally, you’re picked out to play a more substantial part in one scene, and you feel as if maybe the
professional/supporting artist divide isn’t so insurmountable after all. Then, when you’re finally released to go home
at 2 a.m., after walking up and down some stretch of pavement 50 times, and you realize that the actors still have
hours more to go, their job no longer seems quite so glamorous or privileged. Actually, night shoots tend to be the
worst, although the extra money you receive almost makes up for it. Once on the set of a blockbuster, a mix-up in
the costume department resulted in me spending two nights in an aircraft hangar, drinking terrible coffee and
reading books – and getting paid for it. Meanwhile, the other extras all ran around outside in the freezing drizzle
for an action scene. Every time they trudged back in from a take, their very visible fatigue and discomfort made
me feel somewhat fraudulent, aware as I was that we were all being remunerated at the same rate for our efforts.
D. One of the bonuses of being an extra is the free catering. Getting up at 4 a.m. isn’t so bad when you can
go straight in for a large breakfast, and a filling lunch is always provided, though obviously aren’t allowed to eat
anything before the “talent” and the crew. For period dramas, you will also get a free haircut, although this can
sometimes make things awkward. On one shoot, I had to phone in “stick” to my day job, and then had trouble
explaining to my boss the next morning why I now had a 1950s-style haircut. Another plus may be seeing yourself
on screen, usually as a blurry outline to one side or a tiny figure in the distance. That’s what extras do: blend into
the background and not divert attention from the main characters. Would I encourage anyone to sample this life?
Hardly, if the aim is to make money or get into the industry. If, however, you like the idea of dressing up, with the
possibility of glimpsing yourself on the big screen for a few seconds, well, maybe.
