Multiple choice

Fish eating has long been associated with lower risk of cardiac problems. The port city of Logan is also known to be the fish capital of the state and residents can hardly imagine a diet without a helping of fish. Yet the city has a higher proportion of high-risk cardiac cases than the city of Morga where people are not so fond of fish and relish juicy meats.

Which of the following helps resolve the apparently paradoxical situation?

  1. Fish eating is one of the causes of lower risk of cardiac problems.

  2. Some other items may also be salutary for health.

  3. People of Logan prefer only Tuna.

  4. Morga has wider city roads and sparse traffic.

  5. Morga has higher fatality rate for some other ailments.

A Correct answer
Explanation

If fish eating is one of the causes, its favorable effect must have been neutralized by negative effect of other factors. There might be many other factors responsible for higher incidence of cardiac problems.

Multiple choice

In a research study conducted to assess the efficacy of a Health Sweet (H–sweet), 50 diabetics were studied over a period of 6 months. During this period, each person consumed one helping of sweet instead of sugar. They continued to follow their normal diet and fitness regimen for the rest of the day. At the end of the 6 month period, each person’s sugar level had dropped significantly. This clearly demonstrates that any person who uses H–sweet instead of sugar daily, will have lower sugar levels and will feel healthier and fitter.

Which of the following is an assumption on which the argument depends?

  1. H–sweet is effective provided it is taken for 6 months.

  2. Diabetics are likely to experience higher sugar levels if they discontinue H–sweet.

  3. No other alternative to H–sweet will have the same effect.

  4. The fitness regimen was not responsible for drop in sugar levels.

  5. The calorific value of each sweet helping was less than that of sugar avoided.

D Correct answer
Explanation

The true effect of H-sweet can be measured if other sugar controlling factors are removed. Since the fitness regimen & diet control are ongoing, it is possible that drop in sugar levels might be due to those reasons. Full credit to H- Sweet can be given only if (D) is assumed.

Multiple choice

What according to the author does one need to do to prevent withdrawal symptoms?

Directions: Read the passage below and answer the question given underneath.

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 again, 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.
