Coincident with concerns about the accelerating loss of species and habitats has been growing appreciation of the importance of biological diversity, the number of species in a particular ecosystem, to the health of the Earth and human well-being. Much has been written about the diversity of terrestrial organisms, particularly the exceptionally rich life associated with tropical rain-forest habitats. Relatively little has been said, however, about diversity of life in the sea even though coral reef systems are comparable to rain forests in terms of richness of life.

An alien exploring Earth would probably give priority to the planet’s dominants, most-distinctive feature - the ocean. Humans have a bias toward land that sometimes gets in the way of truly examining global issues. Seen from far away, it is easy to realize that landmasses occupy only one-third of the Earth’s surface. Given that two thirds of the Earth’s surface is water and that marine life lives at all levels of the ocean, the total three-dimensional living space of the ocean is perhaps 100 times greater than that of land and contains more than 90 percent of all life on Earth even though the ocean has fewer distinct species.

The fact that half of the known species are thought to inhabit the world’s rain forests does not seem surprising, considering the huge number of insects that comprise the bulk of the species. One scientist found many different species of ants in just one tree from a rain forest. While every species is different from every other species, their genetic makeup constrains them to be insects and to share similar characteristics with 750,000 species of insects. If basic, broad categories such as phyla and classes are given more emphasis than differentiating between species, then the greatest diversity of life is unquestionably the sea. Nearly every major type of plant and animal has some representation there .To appreciate fully the diversity and abundance of life in the sea, it helps to think small. Every spoonful of ocean water contains life, on the order of 100 to 100,000 bacterial cells plus assorted microscopic plants and animals, including larvae of organisms ranging from sponges and corals to starfish and clams and much more.

Question: The passage suggests that most rain forest species are ______.

A. birds

B. bacteria

C. mammals

D. insects

Read the passage below and decide whether the statements are TRUE or FALSE?

Nguyen Tri Hieu, 48, from HCM City has donated blood 71 times. However, he has set a goal of donating blood up to 100 times or until his health no longer allows him to.

“My mother died due to lack of blood for a transfusion when I was 20 years old. My family got together in an effort to donate blood to help her. We even bought blood from other donors, but it was not enough,” he recalled.

“I wasn't just my mother at that time, many patients were in desperate need of blood transfusions but the resources simply weren't there and they had to leave this world before their time.” said Hieu.

A few years after his mother passed away, Hieu decided to register to donate blood. Since the first time in 1997, Hieu has donated blood for 71 times, offering up the life-giving resource once every three months.

“There have been many times when I've donated blood to people in need of urgent transfusions. Once, when I was working, my friend at the blood bank called me to help a child at the Heart Institute. My boss immediately told me to go to the hospital.”

“I remembered all the times I've donated blood like that because if did not hurry, the patient’s life would be at risk," he said.

Hieu is also a registered organ donor. "I feel like I can give something, I don't need to keep it," he said. "I feel like I can give away anything, I should not keep it, how can I do it when someone might need it.”

Hieu was one of 100 donors who were honoured at a ceremony on Thursday for

Question: He always tries to help patient with urgent need of transfusion.

A. True

B. False
