Practice Questions

None' can be singular or plural, but here it refers to 'cake' (uncountable/singular), requiring 'has'.

Along with his friends' is a prepositional phrase, so the subject remains 'brother' (singular).

Necessary' is the correct spelling (one 'c', two 's's).

Could have' is the correct auxiliary verb construction.

You' is a plural pronoun (or used with plural verb forms), so 'are' is correct.

Effect' is the noun form (the result); 'affect' is typically the verb form (to influence).

Most smartest' is a double superlative error. 'Smartest' is already superlative.

Lie' (to recline) has the past participle 'lain'. 'Lay' (to place) has the past participle 'laid'. The books are reclining; therefore, 'lain' is correct.

Lay' requires a direct object (books), whereas 'lie' does not.

Whom' is the object of the verb 'call'.
