Chu Van An High School is one of the oldest and most prestigious state schools in Viet Nam. Established in 1908 by the French, the school was located beside the West Lake, and was originally named after the location it was in. It is a very pleasant, spacious school with great views of the lake from the classroom windows. In 1943, the school was moved to Ninh Binh, and was not moved back to Ha Noi until 1945. In that year, the school was renamed Chu Van An after a famous Vietnamese Confucianism teacher of the Tran Dynasty. Professor Nguyen Gia Tuong became the first Vietnamese principal of the school. Many famous people like ex-Prime Minister Pham Van Dong, Doctor Ton That Tung and poet Xuan Dieu used to be the school's students.

Read the following passage and mark the letter A, B, C, or D on your sheet to indicate the correct answer to each of the questions from 40 to 47.
Microplastics are small plastic pieces less than five millimeters in size. Some microplastics are manufactured, such as the microbeads added to health and beauty products, while others result from larger plastics gradually breaking down. These plastics are pervasive in marine environmets, and they are known to harbour toxic substances such as heavy metals and phthalates.
Since many animals are known to eat microplastics, scientists are concerned about the toxic substances contained within them, as well as their capacity to accumulate within the animals and stop them from absorbing nutients correctly.
Even the largest marine creatures are vulnerable to tiny fragments of plastic littering the world’s oceans. A new study has found whales and whale sharks – the largest fish in the world – are ingesting microplastics in alarming quantities. These creatures are filter feeders, meaning they consume large quantities of small prey by straining them out of the ocean water. In the process, they swallow hundreds to thousands of cubic meters of water daily, meaning there ti the potential for them to take in substanial amounts of microplastic floating in the water.
Recently, plastic pollution has received a lot of attention for its effects on marine animals. In the UK, mircobeads have been banned, and other plastic items such as water bottles and disposable coffee cups have also been in the firing line. However, while scientists argee that plastic pollution is a problem for marine animals, there is still a lot they do not know about magnitude of its impact.
Which of the follonging statements is TRUE according to the passage?




A.Only large marine creatures are affected by plastic pollution.
B.Microplastics have the capacity to help animals absorb nutrients.
C.The impacts of plastic pollution are not fully understood.
D.Heavy metals are one form of microplastics.
