Multiple choice

The phrase 'light up' as used in the passage implies

Directions: Read the passage carefully and answer the question that follows.

When you use tobacco products, nicotine is quickly absorbed into your bloodstream. Within 10 seconds of entering your body, the nicotine reaches your brain. It causes the brain to release adrenaline, creating a buzz of pleasure and energy.
The buzz fades quickly though, and leaves you feeling tired, a little down, and wanting the buzz again. This feeling is what makes you light up the next cigarette. Since your body is able to build up a high tolerance to nicotine, you’ll need to smoke more and more cigarettes in order to get the nicotine’s pleasurable effects and prevent withdrawal symptoms.
This up and down cycle repeats over and over, leading to addiction. Addiction keeps people smoking even when they want to quit. Breaking addiction is harder for some people than others. Many people need more than one try in order to quit. 
Research suggests that children and teens may be especially sensitive to nicotine, making it easier for them to become addicted. The younger the smokers are when they start, the more likely they are to become addicted. In fact, about three out of four high school smokers will become adult smokers.

  1. To become brighter

  3. To light a fire

  4. To add excitement

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Health is about being physically, mentally and socially well. Happiness, mutual understanding, and joy are the factors of mental and social health and if they are not present then a disease free person will be under stress and cannot be called healthy. In the light of these facts we can conclude that (1), (2) and (3) are correct. But as discussed above, option (4) is incorrect.

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Option 4 implies a cause other than ‘tea drinking’ to explain the relationship between the premise and the conclusion. Since tea preference is genetically determined, long life also may be genetically determined rather than being the effect of tea drinking. Genetics is the cause, tea drinking and long life are the effects.
