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 following questions

The principle of use and disuse states that those parts of organisms' bodies that are used grown larger. Those parts that are not tend to wither away. It is an observed fact that when you exercise  particular muscles, they grow. Those that are never used dimish. By examining a man's body, we can tell which muscles he uses and which he doesn't. We may even be able to guess his profession or his reaction. Enthusiasts of the "body- building" cult make use of the principle of use and disuse to "build" their bodies, almost like a piece of sculpture, into whatever unnatural shape is demanded by fashion in this peculiar minority culture. Muscles are not the only parts of the body that respond to use in this kind of way. Walk barefoot and you acquire harder skin on your soles. It is easy to tell a farmer from a bank teller by looking at their hands alone. The farmer's hands are horny, hardened by long exposure to rough work. The teller's hands are relatively soft.

The principle of use and disuse enables animals to become better at the job of surviving in their world, progressively better during their lifetime as a result of living in that world. Humans, through direct exposure to sunlight, or lack of it, develop a skin color which equips them better to survive in the particular local conditions.

Too much sunlight is dangerous. Enthusiastic sunbathers with very fair skins are susceptible to skin cancer. Too little sunlight, on the other hand, leads to vitamin-D deficiency and rickets. The brown pigment melanin which is synthesized under the influence of sunlight, makes a screen to protect the underlying tissues from the harmful effects of further sunlight. If a suntanned person moves to a less sunny climate, the melanin disappears, and the body is able to benefit from what little sun there is. This can be represented as an instance of the principle of use and disuse: skin goes brown when it is "used", and fades to white when it is not.

Just as you designate and separate your physical workspace, you should be clear about when you’re working and when you’re not. You’ll get your best work done and be most ready to transition back to the office if you stick with your regular hours. Plus, if your role is collaborative, being on the same schedule as your coworkers makes everything much easier.

“The biggest difference between working from home and working in the office is that you are in charge of your environment and have to treat yourself like an employee,” Yurovsky says. This means holding yourself accountable, but also recognizing when enough is enough, just as a good manager might. “If you feel yourself extending your work hours because you are not doing anything in the evening...tell yourself it’s time to put work away, recharge, and start tomorrow with a fresh mind. The work will be there in the morning.”

If you live with other people, this separation is even more critical. Communicate with the people whom you live with to establish boundaries so you can cut down on distractions during the workday—and then disconnect and give the people you care about your full attention. Having a separate time and space to work will allow you to be more present in your home life.

Isaac's first published work was a theory of light and color. When another scientist wrote a paper criticizing this theory, Isaac flew into an uncontrollable rage. The scientist (28) ______ for the criticism was a man called Robert Hooke. He was head of the Royal Society, and one of the most respected scientists in the country. (29)_______, this made no difference to Isaac, who refused to speak to him for over a year.

The simple fact was that Isaac found it impossible to have a calm discussion with anyone. As soon as someone said something that he disagreed with, he would lose his temper.
