Spotting Errors

The phrase 'What to speak' is unidiomatic and grammatically incorrect. The correct idiom is 'What to say of' or 'Not to speak of', which means 'let alone' or 'not to mention'. Part (a) contains the grammatical error.

In conditional sentences, when the main clause is in future tense, the conditional clause is in simple present. So, correct phrase is 'growth drops to 7 percent...'

Lesser should be changed to "less". Less is a comparative form of 'little' and when refering to quantitity, 'less' is used. Lesser is used when referring to quality.

(B) he has been leading a luxurious life. Here an adjective should be used which modifies the noun.

'This pen is inferior to that'. The adjectives of comparative degree like Senior, Junior, Prefer, Superior, inferior are always followed by 'to' instead of 'than'.

(senior to). The adjectives of comparative degree like Senior, Junior, Inferior, Superior are always followed by ‘to’ instead of ‘than’.

'He is senior to me in service'. The adjectives of comparative degree like Senior, Junior, Prefer, Superior are always followed by 'to' instead of 'than'.

 ‘Your Metro shoes are superior to mine’. The adjectives of comparative degree like Senior, Junior, Inferior, Superior are always followed by ‘to’ instead of ‘than’.

Delete 'more'. 'Preferable' is comparative in itself so 'more' is redundant.

‘He considers me his sister’ verbs like consider, think, call etc. are not followed by ‘as’.

'Its' in place of 'their'. The pronoun for 'everything' is 'its'.

'More than' should be deleted. Double comparatives are to be avoided. 'Exceed' is sufficient.

 I regard her 'as' my sister. Some verbs like 'regard', 'reject', 'beat' etc. are followed by 'as'.

(yesterday afternoon). The correct phrase is “yesterday afternoon” and not “afternoon yesterday”.

It should read as 'he tried to avoid'. Since the sentence starts in the past tense it should end also in the past tense to maintain parallelism.
