Competitive Exams, Question of the Day August 9th, 2009

The function f(A, B) is a function of two positive integers A and B. It is known that f(1, 0) = f(0, 1), that f(0, k) = k + 1 (for natural number k) and that f(A, B) = f(A − 1, f(A, B − 1)). What is the value of f(1, 1500)?

OPTIONS

	1)	1498
	2)	1499
	3)	1500
	4)	1501
	5)	None of these

Solution for the Previous Question is:

The options are word play with similar and dissimilar and convergence and divergence. A closer examination will help you understand the differences.

Option 1 mentions ‘structure and biology’ which are in the context of the paragraph the same thing- ‘behaviour and biology’ are required.Secondly, its definition of divergence is incorrect.

Option 2, the definition of divergence is incorrect. It should be ‘closely related animals’ and not ‘unrelated animals’.

In option 3 the definition of convergence is incorrect. It should be ‘similar responses to similar environmental conditions’.

In option 4, the definition of convergence is incorrect. It should read ‘similar environmental conditions’ and not ‘dissimilar environmental conditions’.

Option 5 correctly captures the essence of the text.

Hence, the correct answer is option 5.
