  1. A drop in the number of patients is erroneously held responsible for a drop in the cost of treatment.

  2. There is no material difference between fruit taken before or after the main course.

  4. Cost of treatment depends upon severity of the ailment.

  2. believe that sedentary life-styles but not faulty food habits are

  3. believe that it is sedentary life-style but not faulty food habits that are

E Correct answer
Explanation

Explanation for (1): The latter part of the sentence concludes that 'life-style' is the major 'reason' (not reasons) for the problem. This implies that the subject is singular and so, the verb 'are' should be changed to 'is'. Explanation for (2): This option unnecessarily changes the conjunction and turns the subject into plural. Explanation for (3): This option makes unwarranted changes without rectifying the error of S-V agreement. Explanation for (4): This option unnecessarily turns the subject into plural. Justification for (5): The latter part of the sentence concludes that 'life-style' is the major 'reason' (not reasons) for the problem. This implies that the subject is singular and so, the verb 'are' should be changed to 'is'. This option corrects the error.

 The hint to this sentence can be taken from the latter part where the sentence that concludes that 'life style' is the major cause, not causes for the problem. This implies that the subject is singular, and this is the reason why the verb should be singular which we find in (E), the correct option.

Directions: Read the passage and answer the question.

The functional declines of advancing age are depressing. The heart’s ability to pump blood drops about one per cent: blood flow to arms and legs decreases by thirty to forty per cent in old age. The amount of air a person can exhale after a deep breath lessens and the chest wall stiffens with age. However, recent studies have shown that most of these age associated declines can be delayed by exercise. Exercise lowers the resting heart - rate and increases the amount of blood pumped with each beat in older people. When stress is placed on bones through exercise, calcium content rises, with the result that resistance to fracture is improved.

  1. increases the amount of blood pumped by the heart

  2. increases calcium content in bones

  3. increases the amount of air exhaled by a person

Antioxidants protect the body's cells against oxidants or free radicals. These can damage the cell's surface, alter its DNA or completely kill the cell. Oxidants or free radicals cause oxidative stress if the body does not have time to take care of them. It can lead to diseases. A diet naturally rich in antioxidants helps to protect the body.
