Read the following passage and choose the correct answer for each  question.
A healthful lifestyle leads to a longer, happier, healthier life. Staying healthy means eating  a well-balanced diet, getting regular exercise, and avoiding things that are bad for the body and mind.
Nutrition plays a key role in maintaining good health and preventing many diseases. In  spite of all the information available about diets, scientists still believe that good nutrition can be simple. There are several basic rules to follow. Keep fat intake low. Eat foods high in carbo- hydrates, which are the starches in grains, legumes (beans and peas), vegetables, and some fruits. Avoid too much sugar. Limit salt. Eat lots of fruits and vegetables, which are high in  vitamins.
A healthful lifestyle is an active lifestyle. Lack of proper physical exercise can cause tiredness, irritability, and poor general health. Physical fitness requires both aerobic exercise, such  as
running, bicycle riding, and swimming, and muscle-strengthening exercises, such as weight- lifting.
Finally, good health is acquired by saying no to bad habits such as smoking, drinking, and overeating and by avoiding situations that are constantly stressful. People can take their lives and happiness into their own hands. Maintaining a healthy lifestyle is the first  step.

Read the following two passages and choose the correct answer for each  question.
Various types of fog are essentially clouds that form at the earth's surface, produced  by temperature differences and moisture in the air. As warm, moisture-laden air cools, its relative humidity (the amount of moisture that air can contain, which depends on the temperature) increases. Warm air can hold more water vapor than cold air. So if the air is cooled sufficiently it will reach saturation, or the dew point, at which point the moisture begins to condense out of the air and form water droplets, creating  fog.
It can be concluded from the passage that ...... .
A. 
foggy days are caused by cold nights
 
B.fog is likely to form in desert areas
C. 
hot humid days are usually followed by cold, foggy nights
 
D. 
fog could form on a cold evening after a warm day
