[Q]: Context: The male reproductive organs include the penis, testes, and epididymis ( Figure 1.1). The figure also shows other parts of the male reproductive system. The penis is a cylinder-shaped organ. It contains the urethra. The urethra is a tube that carries urine out of the body. The urethra also carries sperm out of the body. This drawing shows the organs of the male reproductive system. It shows the organs from the side. Find each organ in the drawing as you read about it in the text. The two testes (singular, testis) are egg-shaped organs. They produce sperm and secrete testosterone. The testes are found inside of the scrotum. The scrotum is a sac that hangs down outside the body. The scrotum also contains the epididymis. The testes, being in the scrotum outside the body, allow the temperature of the sperm to be maintained at a few degrees lower than body temperature. This is necessary for the stability of these reproductive cells. The epididymis is a tube that is about six meters (20 feet) long in adults. It is tightly coiled, so it fits inside the scrotum. It rests on top of the testes. The epididymis is where sperm grow larger and mature. The epididymis also stores sperm until they leave the body. Other parts of the male reproductive system include the vas deferens and the prostate gland. Both of these structures are pictured below ( Figure 1.1). The vas deferens is a tube that carries sperm from the epididymis to the urethra. The prostate gland secretes a fluid that mixes with sperm to help form semen. The prostate gland is located beneath the bladder. Semen is a "milky" liquid that carries sperm through the urethra and out of the body. In addition to sperm cells, semen contains sugars (fructose) which provide energy to the sperm cells, and enzymes and other substances which help the sperm survive.
Question: what organ or gland sits on top of the testes?
[A]: the epididymis

[Q]: Context: People all over the world today are beginning to hear and learn more and more about the problem of pollution.Pollution is caused either by man's release of completely new artificial substances into the environment,or by releasing greatly increased amounts of a natural substance,such as oil from oil tankers into the sea. The whole industrial process which makes many of the goods and machines we need and use in our daily lives,is bound to create a number of waste products which upset the environmental balance,or the ecological balance as is also known.Many of these waste products can be prevented or disposed of.But while more and more new and complex goods are produced,there will be new,dangerous waste to be disposed of,for example,the waste products from nuclear power stations.Many people,therefore,see pollution as only part of a larger and more complex problem,that is,the whole process of industrial production and consumption of goods.Others again see the problem mainly in connection with agriculture,where new methods are helping farmers grow more and more on their land to feed our ever-increasing population.However,the land itself is gradually becoming worn out as it is being used,in some cases,too heavily,and artificial fertilizers can not restore the balance. Whatever its underlying reasons are,there is no doubt that much of the pollution caused could be controlled if only companies,individuals and governments would make more efforts.In the home there is an obvious need to control litter and waste.Food comes wrapped up three or four times in packages that all have to be disposed of;drinks are increasingly sold in bottles or tins which can not be reused.This not only causes a litter problem,but also is a great waste of resources,in terms of glass,metals and paper.Advertising has helped this process by persuading many of us not only to buy things we neither want nor need,but also to throw away much of what we do buy.Pollution and waste combine to be a problem everyone can help to solve by cutting out unnecessary buying,excessive consumption and careless disposal of the products we use in our daily lives.
Question: Many people see pollution as only part of .
[A]: the whole process of industrial production and consumption of goods
