Câu hỏi: Read the following passage and mark the letter A, B, C, or D to indicate the answer to each of the question.
Although bear-like, koalas are not bears. They are mammals, so feed their young milk and are marsupials, which means that their babies are born immature and they develop further in the safety of a pouch. They are tree-dwelling, herbivorous marsupials, which average about 9kg in weight and live on gum leaves. Their fur is thick and usually ash grey with a tinge of brown in places. Koalas in the southern parts of Australia are considerably larger and have thicker fur than those in the north. This is thought to be an adaptation to keep them warm in the colder southern winters.
Younger breeding females usually give birth to one joey each year, depending on a range of factors. The joey stays in its mother's pouch for about 6 or 7 months, drinking only milk. After venturing out of the pouch, the joey rides on its mother's abdomen or back, although it continues to return to her pouch for milk until it is too big to fit inside. The joey leaves its mother's home range between 1 and 3 years old, depending on when the mother has her next joey.
Koalas are mostly nocturnal. They sleep for part of the night and also sometimes move about in the daytime. They often sleep for up to 18-20 hours each day. There is a myth that koalas sleep a lot because they 'get drunk' on gum leaves. However, most of their time is spent sleeping because it requires a lot of energy to digest their toxic, fibrous, low-nutrition diet and sleeping is the best way to conserve energy.
The koala gets its name from an ancient Aboriginal word meaning "no drink" because it receives over 90% of its hydration from the eucalyptus leaves (also known as gum leaves) it eats, and only drinks when ill or times when there is not enough moisture in the leaves i.e. during droughts, etc.
According to paragraph 2, how do younger mother koalas usually breed ?
A. They give birth to one joey biannually.
B. They give birth to one offspring annually.
C. They don't give birth until the females reach 6 or 7 months.
D. They don't breed during the day.
