The following appeared in a fitness magazine.

"It has long been known that getting at least 8 hours of sleep is good for health. But a recent 5-year study of adult sleeping habits found that people who reported sleeping 8 or more hours had a higher rate of specific health-related problems than did those who reported sleeping 7 hours. People who reported sleeping 5 hours also had a slightly increased rate of the same specific health-related problems. Clearly, people should try to get 7 hours of sleep, and they should worry more about getting too much sleep than too little."

Solutions & Explanations:

1) D.
DIURNAL = of or belonging to or active during the day
NOCTURNAL = belonging to or active during the night.

2) E.

EXEMPT = To free from an obligation or duty.
LIABILITY = A condition of owing something to another, i.e. to have an obligation.
LINK between EXEMPT and LIABILITY = opposites - to exempt is to free somebody from a liability.

(A) flout: authority (flout = To refuse or fail to obey. Which is not to free from authority.)
(B) bestow: reward (bestow = To give formally or officially. Which is not an opposite of reward.)
(C) permit: request (permit is given upon request, so permit is not to free from request.)
(D) restrain: disorder (restrain = To control, restrict, or arrest. Not related to disorder as exempt is related to liability.)
(E) pardon: penalty (pardon is something that can be done to free from penalty. So, this pair has the same link as does the exempt:liability pair)

3) E.
"Unjustified malpractice claims" is the key to solve this question. Physicians (doctors) are sometimes attacked with claims of unjustified practice. Therefore, objectively set standards, can safeguard them from such claims, and thus give them protection from such claims.
"Providing them" helps to understand that the topic is for, rather than against physicians, so "test" and trial" are rulled out immediately. B and C are just not logical pairs to fill in the blanks.

4) 1000 is larger than the number of light-years that the star is away from the Sun.
A light-year is the distance that light travels in one year, or approximately 9.5×10¹² kilometers. A certain star is 2.4×10¹⁵ kilometers away from the Sun.
Basically, the approach is: How many light-years away is that star from the Sun?
The calculation is simple: 2.4×10¹⁵ / 9.5×10¹² = (2.4 / 9.5) × 10³, which is smaller than 1000 (10³), because it is multiplied by something that is smaller than 1 (2.4 / 9.5).

5) E.

The starting level on Tuesday was 18.5, and the level was almost 21 on Wednesday.
This makes the net difference, of about 2.5. That is 2.5 per 24hrs. Which is approximately 0.25 per hour.
