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

A person will be healthy if he eats a proper diet (option 3), lives in a hygienic environment (option 4) and keeps his body fit by exercising regularly (option 1). Thus, options (1), (3) and (4) help a person to be healthy as these habits keep the germs away and thus, reduce the chances of getting infected by diseases. But, drinking alcohol is not a healthy practice as it adversely affects the nervous system and its prolonged consumption adversely affects the liver and general body health. Thus, (2) is the correct answer because drinking alcohol is responsible for the ill health of a person.

Multiple choice

Directions: In the given question, select the option that expresses the central idea in the most clear, concise and correct manner.

  1. Several studies have found that the heart patients who exercise most actively have half or less than half the chance of dying of a heart attack as those who are sedentary.

  2. Several studies have found that the heart patients who exercise most actively are at least fifty percent less likely than those who are sedentary to die of a heart attack.

  3. Several studies have found that the heart patients who exercise most actively have half the chance that they will die of a heart attack, or less than who are sedentary do.

  4. Several studies have found that the heart patients who exercise most actively are at least fifty percent less likely to die of a heart attack as those who are sedentary.

  5. Several studies have found that the heart patients who exercise most actively have half the chance that they will die of a heart attack, or less as those who are sedentary.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The sentences compare the chances of a heart attack between heart patients who exercise and those who do not. So, the concoction introducing comparison, 'than' should be used. This is seen only in sentences (2) and (3). In sentence (3), the word order is incorrect. Hence, (2) is the answer.

Multiple choice

Directions: Read the passage given below and answer the question that follows it.

A recent medical journal published a study, which found that athletes who exercised more than five hours per week were more likely than the other athletes to have high levels of chemical compound riboflavin in their blood. High levels of this compound can be one of the first warning signs of skin cancer, which is almost always caused by excessive exposure of the body to water.

Which one of the following, if true, would cast doubt on the study’s conclusion that exercising more than five hours per week increases the odds of contracting skin cancer?

  1. Lack of exercise increases the rate of absorption of many dangerous chemical compounds into the blood stream.

  2. Exercise increases the rate of blood flow through the circulatory system, thereby increasing the rate at which contaminants spread through the body.

  3. Majority of the athletes studied were swimmers.

  4. Athletes contract skin cancer at a significantly higher rate than common people do.

  5. None of these

Reveal answer Fill a bubble to check yourself

Chronic diseases, by definition, are long-lasting conditions (typically persisting for 3+ months or years). They often result in weight loss, fatigue, and restlessness. The statement that chronic diseases 'last for short duration' is incorrect - this contradicts the fundamental definition of 'chronic', which means continuing for a long time, unlike acute diseases which are short-term.
