Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the questions
Universities love overseas students – they are clever and hardworking, they bring different cultures to seminars and student life and they pay their way. In Britain, universities are getting ready to enroll more overseas students. The British Council has published a report predicting that overseas student numbers could soar to more than 800,000 by 2018. In 2010, figures put the total at over 400,000 international students out of two and a half million students in UK higher education and it is clear that this influx is having an enormous impact on universities and colleges. These students bring welcome fees, of course, but they are also likely to be very intelligent students who inject new cultural influences and bring changes to the old university systems. Their demand for vocational subjects such as business, biotechnology and information technology, rather than traditional academic subjects, is affecting what is taught as well.
The impressive expansion of foreign students has already had a significant impact on higher education. Overseas student numbers, including European Union students, have risen from 270,000 in 2002 to 400,000 in 2010. During this time the number from China jumped more than tenfold, and numbers from India have been going up. In contrast, the number of students from other countries has fallen, reflecting their governments’ efforts to educate more of their young people at home, as well as competition from Australia and the USA. But as the Asian tiger economies expand their own universities, the good news for places like the London School of Economics is that there are more and more graduates looking to improve _their_ qualifications or to pursue research in their subjects.

According to the passage, which of the following is _TRUE_?
Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the questions
People have been donating blood since the early twentieth century to help accident victims and patients undergoing surgical procedures. Usually a pint of whole blood is donated, and it is then divided into platelets, white blood cells, and red blood cells. People can donate blood (for red blood cells) about once every two
months. Transfusing the blood from the donor to the recipient is straightforward. It involves taking the blood from a donor’s arm vein by means of a hypodermic syringe. The blood flows through a plastic tube to a collection bag or bottle that contains sodium citrate, which prevents the blood from clotting. When the blood is given to a patient, a plastic tube and hypodermic needle are connected to the recipient's arm. The blood flows down from the container by gravity. This is a slow process and may last as long as 2 hours to complete the infusion of blood into the recipient. The patient is protected from being infected during the transfusion. Only sterile containers, tubing, and needles are used, and this helps ensure that transfused or stored blood is not exposed to disease causing bacteria. Negative reactions to transfusions are not unusual. The recipient may suffer an allergic reaction or be sensitive to donor leukocytes. Some may suffer from an undetected red cell incompatibility. Unexplained reactions are also fairly common. Although they are rare, other causes of such negative reactions include contaminated blood, air bubbles in the blood, overloading of the circulatory system through administration of excess blood, or sensitivity to donor plasma or platelets. Today, hospitals and blood banks go to great lengths to screen alt blood donors and their blood. All donated blood is routinely and rigorously tested for diseases, such as HIV, hepatitis B, and syphilis. When the recipient is a newborn or an infant, the blood is usually irradiated to eliminate harmful elements. Donated blood is washed, and the white blood cells and platelets removed. Storing the blood sometimes requires a freezing process. To freeze the red blood cells, a glycerol solution is added. To unfreeze the, the glycerol is removed. The ability to store blood for long periods has been a boon to human health.
All of the following are mentioned as potential negative reactions to transfusion _EXCEPT_ .

People have been donating blood since the early twentieth century to help accident victims and patients undergoing surgical procedures. Usually a pint of whole blood is donated, and it is then divided into platelets, white blood cells, and red blood cells. People can donate blood (for red blood cells) about once every two
months. Transfusing the blood from the donor to the recipient is straightforward. It involves taking the blood from a donor’s arm vein by means of a hypodermic syringe. The blood flows through a plastic tube to a collection bag or bottle that contains sodium citrate, which prevents the blood from clotting. When the blood is given to a patient, a plastic tube and hypodermic needle are connected to the recipient's arm. The blood flows down from the container by gravity. This is a slow process and may last as long as 2 hours to complete the infusion of blood into the recipient. The patient is protected from being infected during the transfusion. Only sterile containers, tubing, and needles are used, and this helps ensure that transfused or stored blood is not exposed to disease causing bacteria. Negative reactions to transfusions are not unusual. The recipient may suffer an allergic reaction or be sensitive to donor leukocytes. Some may suffer from an undetected red cell incompatibility. Unexplained reactions are also fairly common. Although they are rare, other causes of such negative reactions include contaminated blood, air bubbles in the blood, overloading of the circulatory system through administration of excess blood, or sensitivity to donor plasma or platelets. Today, hospitals and blood banks go to great lengths to screen alt blood donors and their blood. All donated blood is routinely and rigorously tested for diseases, such as HIV, hepatitis B, and syphilis. When the recipient is a newborn or an infant, the blood is usually irradiated to eliminate harmful elements. Donated blood is washed, and the white blood cells and platelets removed. Storing the blood sometimes requires a freezing process. To freeze the red blood cells, a glycerol solution is added. To unfreeze the, the glycerol is removed. The ability to store blood for long periods has been a boon to human health.
