The first is a context in which the aruthor argues his conclusion and the second is the conclusion.

In a country, the number of days is calculated as follows: heavy rainfall days when rain falls more than 2 inches, moderate rainfall when rain falls more than 1 inch but less than 2 inch, light rain fall when rain falls less than 1 inch and no rainfall. As compared to 1991, the number of moderate rainfall days and that of light rainfall days were fewer in 1990. But the total amount of rainfall in 1990 was 20% greater than in 1991.
If the statements above are true, it is possible that
(A) the number of heavy rainfall days in 1990 was fewer than in 1991.(o)
(E) the average amount of monthly rainfall in 1990 was less than in 1991.(x)

Although a new product, -----, will help fish gain weight faster than a---, this benefit doesn’t compensate for the cost increase. However, the manufacturer predicts that the new product will be commercially successful for farmed fish.
