Read the passage and choose the best option for each sentence

In the United States, presidential elections are held in years evenly divisible by four (1888, 1900, 1964, etc.). Since 1840, American presidents elected in years ending with zero have died in office, with one exception. William H. Harrison, the man who served the shortest term, died of pneumonia only several weeks after his inauguration.

Abraham Lincoln was one of four presidents who were assassinated. He was elected in 1860, and his untimely death came just five years later. James A. Garfield, a former Union army general from Ohio, was shot during his first year in office (1881) by a man to whom he wouldn't give a job. While in his second term of office (1901), William McKinley, another Ohioan, attended the Pan-American Exposition in Buffalo, New York. During the reception, he was assassinated while shaking hands with some of the guests. John F. Kennedy was assassinated in 1963 in Dallas only three years after his election.

Three years after his election in 1920, Warren G, Harding died in office. Although it was never proved, many believe he was poisoned. Franklin D. Roosevelt was elected four times (1932,1936, 1940 and 1944), the only man to serve so long a term. He had contracted polio in 1921 and eventually died of the illness in 1945.

Ronald Reagan, who was elected in 1980 and reelected four years later, suffered an assassination attempt but did not succumb to the assassin's bullets. He was the first to break the long chain of unfortunate events. Will the candidate in the election of 2020 also be as lucky?

The word "whom" in the second paragraph refers to _______

A. Garfield          

B. a Union army general         

C. McKinley                  

D. Garfield's assassin

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 30 to 34.

In addition to providing energy, fats have several other functions in the body. The fat soluble vitamins, A, D, E and K, are dissolved in fats, as their name implies. Good sources of these vitamins have high oil or fat content, and the vitamins are stored in the body's fatty tissues. In the diet, fats cause food to remain longer in the stomach, this increasing the feeling of fullness for some time after a meal is eaten. Fats add variety, taste, and texture to foods, which accounts for the popularity of fried foods. Fatty deposits in the body have an insulating and protective value. The curves of the human female body are due mostly to strategically located fat deposits.

Whether a certain amount of fat in the diet is essential to human health is not definitely known. When rats are fed a fat-free diet, their growth eventually ceases, their skin becomes inflamed and scaly, and their reproductive systems are damaged. Two fatty acids, linoleic and arachidonic acids, prevent these abnormalities and hence are called essential fatty acids. They also are required by a number of other animals but their roles in human beings are debatable. Most nutritionists consider linoleic fatty acid an essential nutrient for humans. 

The author states that fats serve all the following body functions EXCEPT to 

A. promote a feeling of fullness 

B. insulate and protect the body 

C. provide energy 

D. control weight gain
