Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 36 to 42.

Jonas Salk is the American physician and medical researcher who developed the first safe and effective vaccine for poliomyelitis. Salk received his M.D. in 1939 from New York University College of Medicine, where he worked with Thomas Francis Jr., who was studying how to develop vaccines from killed viruses. Salk joined Francis in 1942 at the University of Michigan School of Public Health and became part of a group that was working to develop a vaccine against influenza.

In 1947, Salk became associate professor of bacteriology and head of the Virus Research Laboratory at the University of Pittsburgh School of Medicine, where he began research on poliomyelitis. Working with scientists from other universities in a program to classify the various strains of the polio virus, Salk corroborated other studies in identifying three separate strains. He then demonstrated that killed virus of each of the three, although incapable of producing the disease, could induce antibody formation in monkeys.

In 1952, he conducted field tests of his killed-virus vaccine, first on children who had recovered from polio and then on subjects who had not had the disease. The results of both tests showed that the children’s antibody levels rose significantly and no subjects contracted polio from the vaccine. His findings were published the following year in the Journal of the American Medical Association. In 1954, a mass field trial was held, and the vaccine, injected by needle, was found to safely reduce the incidence of polio. On April 12,1955, the vaccine was released for use in the United States. Salk served successively as professor of bacteriology, preventive medicine, and experimental medicine at Pittsburgh, and in 1963, he became fellow and director of the Institute for Biological Studies in San Diego, California, later called the Salk Institute. Among many other honors, he was awarded the Presidential Medal of Freedom in 1977.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 31 to 35.

Banking and banks are very important for the functioning of the modern world. Without banks the way we use money would not work. Banks enable people to save money, borrow money and to pay for things with ease and security.

Each country in the world has its own well known banks that have branches in nearly every city so that they are convenient for people to use. People often have to visit the local branch of the bank when they want certain services. There are also some very big multinational banks that have branches in most countries in the world.

As well as the local branches that are in most cities, each bank will also have a head office. This is where all central tasks are performed that let the local branches function. The people that work in the branches will be the bank manager, the person in charge, and various tellers who work behind the bank counter and help the customers. There will also likely be security guards to protect the money, workers and customers. 

Most customers will just need to see the tellers when they qo to the bank if they are payinq money into their account as either cash or a check. However, they might need to see the bank manager if they want to open an account or if they have become overdraw, when they have spent more money than there was in the account. Also if they want to borrow money and get a loan the person will need to see the bank manager who will have to approve it.

As well as being able to use cash or checks to pay for things, banks also offer their customers the more convenient methods of using either a debit card or credit card. These methods are very convenient as you just need to carry a small plastic card to be able to pay for anything. When paying with plastic you will need to either sign a receipt or enter a PIN number to conform the purchase and that you are authorized to use the card
