Directions: Select the most appropriate filler(s) for the blank(s) such that the sentence makes coherent sense.

Having ____________ economic significance, sericulture has become an employment ___________ for the poor and the weaker sections of society including widows.

For the first blank, all the answer choices seem probable. As all these choices are positive, therefore the second blank would be replaced by a positive word (as second part of the sentence is in support to the first part). 'Contingency' (possibility, likelihood) in (1) is not in tandem with it's other pair word 'immense', hence ruled out. On the same lines, 'consistency'(harmony, agreement) in (2) is ruled out. 'Potential' is power, potent, which on replacing the blank gives a cogent meaning to the sentence. 'capacity' in (4) is ruled out as the sentence becomes absurd on use of this term. 'Retention' is custody, withholding,; therefore ruled out as completely off the track. Hence, (3) is the correct answer.
