Directions: From the alternatives given, choose the one which will be a suitable substitute for the underlined expression in each of the following.

The unbearably conceited behaviour of the servant made him lose his job whenever he got one.

The meaning of expression 'unbearably conceited' is an attitude having exaggerated opinion of oneself, which cannot be tolerated. So this expression has to be replaced by terms given. Lets analyze various options: (1) indecent, is incorrect because it means something morally offensive, this is not something conceited. (2), impatient is lack of patience but this can't be termed as something conceited. Some reasoning applies to option (4). Only option (3) insufferable seems a valid answer here because it means not sufferable or intolerable which can easily fit in the sentence giving same meaning as before substitution.
