Read the following passage and mark the letter A, B, C, or D on your answer answer to each of the questions

An air pollutant is defined as a compound added directly or indirectly by humans to the atmosphere in such quantities as to affect humans, animals, vegetation, or materials adversely . Air pollution requires a very flexible definition that permits continuous change. When the first air pollution laws were established in England in the fourteenth century, air pollutants were limited to compounds that could be seen or smelled – a far cry from the extensive list of harmful substances known today. As technology has developed and knowledge of health aspects of various chemicals has increased, the list of air pollutants has lengthened. In the future, even water vapor might be considered an air pollutant under certain conditions. Many of more important air pollutants such as sulfur oxides, carbon monoxide, and nitrogen oxides, are found in nature. As the Earth developed, the concentrations of these pollutants were altered by various chemical reactions; they became components in biogeochemical cycle. Theseserve as an air purification scheme by allowing the compounds to move from the air to the water or soil on a global basis, nature's output of these compounds dwarfs that resulting from human activities.

However, human production usually occurs in a localized area, such as a city. In this localized regions, human output may be dominant and may temporarily overload the natural purification scheme of the cycle. The result is an increased concentration of noxious chemicals in the air. The concentrations at which the adverse effects appear will be greater than the concentrations that the pollutants would have in the absence of human activities. The actual concentration need not be large for a substance to be a pollutant; in fact the numerical value tells us little until we know how much of an increase this represents over the concentration that would occur naturally in the area. For example, sulfur dioxide has detectable health effects at 0.08 parts per million (ppm), which is about 400 times its natural level. Carbon monoxide, however, as a natural level of 0.1 ppm and is not usually a pollutant until its level reaches about 15 ppm.

Which of the following is best supported by the passage?

A. To effectively control pollution local government should regularly review their air pollution laws.

B. One of the most important steps in preserving natural lands is to better enforce air pollution laws.

C. Scientists should be consulted in order to establish uniform limits for all air pollutants.

D. Human activities have been effective in reducing air pollution.

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 has never registered to be an organ donor.

A. True

B. False
