the length and width of the lake

C
the depth of the lake

D
the number of fish caught per day

Answer 1

Answer:

according to me the answer is supposed to option D

Answer 2

The question that is asked is how a person will try to estimate the quantity of fish he will catch and the correct option will be A.

• Let us take the options that have been given to us and understand them one by one.
• Let us start with the last option that is given.
• The last option says ' the number of fish caught per day ' and this will definitely affect the estimate of fish caught as if more fish are caught in one day the estimate can be more and vice-versa.
• The second last option says 'the depth of the lake' and this will also have an effect on the estimate as if the depth is more there will be more fishes available to catch and vice-versa.
• The third last option says ' the length and width of the lake ' and this is similar to the explanation given above.
• The first one says  'the average number of fish per square mile' this is the one factor that will not affect the estimate as if more fish are not caught in one particular area the area can be easily changed.
• So, therefore, the correct answer is A. which states the average number of fish per square mile.
