Writing Skill and Proofreading

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

Every one' is a singular subject.

Past tense 'went' is required for the adverb 'yesterday'.

When members of a collective noun act individually (are divided), the plural verb and pronoun are appropriate.

Exaggerate' is the correct spelling.

Neither' is singular, so it requires 'knows'.

Wish' clauses take the subjunctive mood ('were') for hypothetical situations.

The subject is 'bag' (singular).

Each' is singular.

Separate' (a-rate) is correct.

The first sentence contains a dangling modifier. 'Because it was a sunny day' is a correct introductory clause.

Many reasons' is plural, so 'are' must be used instead of 'is'.

A comma is required after an introductory dependent clause.

More taller' is a double comparative error. The correct form is 'taller'.

Between' is a preposition, so it must be followed by object pronouns ('you and me').

Sojourn' is the correct spelling.

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

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

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