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.

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
