In this context, 'after' is a preposition of time indicating that the action of going home occurred following the conclusion of the school day. 'For' and 'since' do not make logical sense in this simple past construction describing a sequence of events.

The preposition 'since' is used with the present perfect tense to refer to a specific point in time (yesterday) when an action or state began. 'For' would require a duration (e.g., for two days), making 'since' the only correct choice.

The preposition 'for' is used to indicate a duration or period of time (more than three years). 'Since' is used for a specific starting point in time, and 'after' does not fit the grammatical structure of the present perfect negative used here.

In English, 'for' is the correct preposition to use with a duration of time like 'a long time'. 'Since' requires a specific point in time (e.g., 'since 2010').

The preposition 'for' is used to indicate a duration of time ('three weeks'). 'Since' is used for a specific point in time, making it incorrect in this context.

'For' is correct with duration phrases like 'many years' when describing how long an action has continued. 'Since' would require a specific starting point (a date or year), not a duration. 'After' would change the meaning.

The preposition 'for' is used to indicate the length of a period of time ('two days'). 'Since' would be used for a specific start time, like 'since Monday'.

The word 'since' is used as a conjunction to introduce a clause describing the starting point of a state that continues to the present. 'For' cannot be used to introduce a clause with a subject and verb.

The preposition 'for' is used to describe a duration of time ('ten years'). 'Since' is incorrect here because 'ten years' is a length of time, not a specific calendar date or event.

'Since' is correct because it marks the point in time (when he was elected) from which the action continues. 'New ideas have been put into practice' (present perfect) + starting point requires 'since'. 'For' would need a duration.

The preposition 'since' is used to refer to a specific point in time (noon) when an action started and continues to the present. 'For' would require a duration (e.g., 'for two hours').

The preposition 'for' is used to indicate a duration or period of time (e.g., 'quite a long time'). 'Since' is used for a specific starting point in time, which does not apply here.

'Since' is correct because it marks the starting point (early this morning) of an action continuing to the present. 'He's been working' (present perfect continuous) requires 'since' + point in time. 'For' would need a duration like 'for 6 hours'.

This is a logic puzzle. C sees two hats; if they were the same, C would know his own. Since C is silent, the hats on A and B must be different. B, seeing A's hat and knowing C is silent, deduces his hat must be the opposite of A's.

'Information' is an uncountable noun and cannot be pluralized. 'Informations' is grammatically incorrect. The sentence should read 'This guide gives useful information about the city.' Option B 'Incorrect' correctly identifies the error.

The sentence is grammatically correct. 'Glanced at' is the correct phrasal verb, and 'seated next to her' is a correctly reduced relative clause describing the man.

The sentence is incorrect because of word order. When a verb has both a direct object ('a beautiful Christmas card') and an indirect object ('her teacher'), the indirect object usually follows the direct object with 'to', or precedes it without 'to'. It should be 'She sent a beautiful Christmas card to her teacher'.

The sentence is grammatically correct. 'The law states' is a standard opening, and 'forbidden in most public areas' correctly uses the passive participle to describe the status of smoking.

This sentence correctly uses 'either' in a negative addition. When adding a negative thought to a previous negative statement, 'neither' (with inversion) or 'not... either' is used. 'My brother hasn't either' is perfectly correct.

The subject is 'One', which is singular. The prepositional phrase 'of you' does not change the number of the subject. Therefore, the singular verb 'has' is required for agreement.
