6.(c) ‘For being late’ in place of ‘to be late’
7.(a) ‘Sweet’ in place of ‘sweetly’. Sweetly is an adverb and an adjective should be used here.
8.(a) ‘All his daughters’ in place of ‘His all daughters’. Here the error is in placement of words.
9.(c) Here the words ‘who are’ create confusion. It is not clear whether the words are for the police or for the men who have been arrested. Such tags cause confusion and should be avoided.
10.(c) ‘Than that of’ in place of ‘than your’.
Here the comparison is between the price of the two cars. Thus ‘that of’ or ‘the price of’ should be used.
