Read the following passage about powering and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions from 31 to 40. 

TikTok is a popular social media app where people can create and share short videos [I]. It started in China in 2016 as Douyin [II]. The app is known for its easy-to-use tools that let users add music, effects, and filters to their videos [III]. People of all ages enjoy making and watching TikTok videos, which can be funny, educational, or creative [IV].

One of the reasons TikTok is so popular is because of its algorithm, which shows users videos that match their interests. When you open the app, you see a personalized feed called the "For You" page. This page is different for everyone and updates with new videos all the time. Users can also follow their favorite creators to see more of their content.

TikTok has become a platform for trends and challenges. Many users participate in dance challenges, lip-syncing, and other viral activities. These trends can spread quickly, reaching millions of people in a short time. Because of this, TikTok has influenced music charts, fashion, and even language. Songs that go viral on TikTok often become hits on other platforms too.

The app is also a space for education and advocacy. Many creators use TikTok to share knowledge about various topics, such as science, history, cooking, and fitness. Others use the platform to raise awareness about social issues and promote positive change.

In addition to individual creators, many brands and businesses use TikTok for marketing. They create content to engage with their audience, often using popular trends and challenges to promote their products.

However, TikTok has faced some criticism and challenges. Concerns about privacy and data security have led to scrutiny from governments. Despite these issues, TikTok still remains one of the most downloaded apps in the world.

The word their in paragraph 2 refers to ______.

Read the passage carefully. Choose an option (A, B, C, or D) that best answers each question from to 646 to 650:

1. Millions of people are using cellphones today. In many places, it is actually considered unusual not to use one. In many countries, cellphones are very popular with young people. They find that the phones are more than a means of communication - having a mobile phone shows that they are cool and connected.

2. The explosion in mobile phone use around the world has made some health professionals worried. Some doctors are concerned that in the future many people may suffer health problems from the use of mobile phones. In England, there has been a serious debate about this issue. Mobile phone companies are worried about the negative publicity of such ideas. They say that there is no proof that mobile phones are bad for your health.

3. On the other hand, medical studies have shown changes in the brain cells of some people who use mobile phones. Signs of change in the tissues of the brain and head can be detected with modern scanning equipment. In one case, a traveling salesman had to retire at young age because of serious memory loss. He couldn't remember even simple tasks. He would often forget the name of his own son. This man used to talk on his mobile phone for about six hours a day, every day of his working week, for a couple of years. His family doctor blamed his mobile phone use, but his employer's doctor didn't  agree.

4. What is it that makes mobile phones potentially harmful? The answer is radiation. High-tech machines can detect very small amounts of radiation from mobile phones. Mobile phone companies agree that there is some radiation, but they say the amount is too small to worry about.

5. As the discussion about their safety continues, it appears that it's best to use mobile phones less often. Use your regular phone if you want to talk for a long time. Use your mobile phone only when you really need it. Mobile phones can be very useful and convenient, especially in emergencies. In the future, mobile phones may have a warning label that says they are bad for your health. So for now, it's wise not to use your mobile phone too often.

According to the passage, what can be inferred about cellphones?
