Though the overall figure for PHCs without

Solution

Though the overall figure of PHCs without electricity supply (5 per cent) may appear to be low, what is of concern is that these PHCs are concentrated in a handful of states-mostly those with poor rural health infrastructure. A-The correct preposition used here should be ‘of’ instead of ‘for’. ‘Of’ refers to belonging to, connected with. ‘The figure belongs to PHCs’. B-Certain auxillary verbs such as can/ may must be followed by base form of verb. Hence, ‘may appear to be’ is correct instead of ‘may appearing to be’. D-The article ‘a’ should be used before ‘handful’ as the PHCs are concentrated in a small amount of states, i.e., ‘a handful of states’.
