Present Simple Third Person

Respuesta correcta: A) She works in a clinic in Carolina.

• A) She works in a clinic in Carolina.Correct! 'She works' carries the -s of the third person singular, and every other option either drops that ending or builds a different tense.
• B) She work in a clinic in Carolina.Incorrect! 'She work' leaves the verb bare while the subject 'she' is third person singular, so the -s of that person is missing.
• C) She working in a clinic in Carolina.Incorrect! 'Working' is a present participle, and a participle only stands on its own after the auxiliary 'is'.
• D) She are working in a clinic in Carolina.Incorrect! 'Are working' needs a plural subject, and 'she' is singular, so two separate rules fail at once.

Respuesta correcta: C) goes

• A) goIncorrect! The bare 'go' is the first person form; a singular third person subject demands 'goes' in this gap.
• B) goingIncorrect! 'Going' is the -ing form, which requires the auxiliary 'is' and can never stand alone here.
• C) goesCorrect! 'Go' ends in -o, so the third person singular adds -es and the form becomes 'goes'.
• D) goneIncorrect! 'Gone' is the past participle, which needs 'have' and describes a finished action rather than a weekly routine.

Respuesta correcta: B) Does your sister live in Ponce?

• A) Do your sister live in Ponce?Incorrect! 'Do' is the auxiliary of the first and second persons, so it cannot agree with the singular 'your sister'.
• B) Does your sister live in Ponce?Correct! 'Does' already holds the -s of the third person singular, and that is why the main verb returns to 'live'.
• C) Is your sister live in Ponce?Incorrect! After 'is' the verb 'to be' can never be followed by 'live' in its base form, so the auxiliary is wrong here.
• D) Your sister does lives in Ponce?Incorrect! The auxiliary 'does' must open the sentence before the subject, so this is not question word order.

Respuesta correcta: D) doesn't drink

• A) don't drinkIncorrect! 'Don't' is reserved for I, you, we and they; a third person singular subject requires 'doesn't'.
• B) isn't drinkIncorrect! 'Isn't' is the negative of the verb 'to be', and no participle follows it in this tense.
• C) not drinkIncorrect! A negative with an action verb always needs an auxiliary, so 'not drink' can never stand alone.
• D) doesn't drinkCorrect! The negative of 'do' in the third person singular is 'doesn't', and it already carries the -s.

Respuesta correcta: D) passes

• A) passsIncorrect! 'Passs' has three s sounds, and no English verb in this form exists; the spelling rule allows only one.
• B) passIncorrect! 'Pass' is the bare form, and the third person singular of 'to pass' must show the -es ending.
• C) passingIncorrect! 'Passing' is the present participle, which belongs to the progressive after the auxiliary 'is'.
• D) passesCorrect! A verb ending in -ss takes the plain -es ending, so the third person singular here is 'passes'.

Respuesta correcta: B) tries

• A) trysIncorrect! 'Trys' writes the third person with a single -s, but a consonant plus -y requires -ies instead.
• B) triesCorrect! 'Try' ends in a consonant followed by -y, so the third person singular is written 'tries'.
• C) tryesIncorrect! 'Tryes' keeps the -y and adds -es, which no English spelling rule allows.
• D) tryingIncorrect! 'Trying' is the participle used after 'is', and this gap asks for the simple present third person.

Respuesta correcta: A) She has a car in Carolina.

• A) She has a car in Carolina.Correct! 'Has' is the third person singular of the irregular verb 'have', and no -s is added to that full form.
• B) She haves a car in Carolina.Incorrect! 'Haves' treats the verb as if it were regular, but 'have' is irregular and its third person is 'has'.
• C) She have a car in Carolina.Incorrect! 'Have' is the bare form, and the singular subject 'she' requires the third person form instead.
• D) She having a car in Carolina.Incorrect! 'Having' is the participle of the perfect progressive, so it would need 'has been' in front of it.

Respuesta correcta: C) live

• A) livesIncorrect! 'Lives' carries the -s of the third person singular, and 'my parents' is a plural subject here.
• B) live'sIncorrect! English never writes a plural with an apostrophe, so 'live's' is not a possible form.
• C) liveCorrect! 'My parents' is plural, and the plural of the present simple adds nothing to the base verb.
• D) livedIncorrect! 'Lived' is the past simple, and the statement describes where they live now, not a finished past action.

Respuesta correcta: C) Doesn't he like mango?

• A) Don't he like mango?Incorrect! 'Don't' cannot pair with the third person pronoun 'he'; the auxiliary of the negative is 'doesn't'.
• B) Isn't he likes mango?Incorrect! After 'is' the verb 'to be' cannot be followed by 'likes', so 'Isn't he likes' is not a form English uses.
• C) Doesn't he like mango?Correct! A negative question opens with 'doesn't he', and the main verb returns to the base form 'like'.
• D) Does he not likes mango?Incorrect! In a negative question the -s belongs to the auxiliary 'Does', never to the main verb, which stays in its base form after 'not'.

Respuesta correcta: A) Does

• A) DoesCorrect! 'Does' is the auxiliary that forms questions with a third person singular subject such as 'your teacher'.
• B) DoIncorrect! 'Do' forms questions with I, you, we and they, and it never carries the third person ending.
• C) IsIncorrect! 'Is' only works with the verb 'to be', and the main verb in this sentence is the action verb 'speak'.
• D) AreIncorrect! 'Are' is the plural auxiliary, so it disagrees with the singular subject 'your teacher'.

Respuesta correcta: D) leaves

• A) leaveIncorrect! 'Leave' is the bare form, and a singular subject such as 'the train' requires 'leaves'.
• B) leavingIncorrect! 'Leaving' is the -ing form and can never stand here without the auxiliary 'is'.
• C) is leaveIncorrect! 'Is leave' mixes the auxiliary 'to be' with a base verb, which is not a form English uses.
• D) leavesCorrect! 'The train' is a singular third person subject, so 'leaves' carries the required -s.

Respuesta correcta: B) has got

• A) have gotIncorrect! 'Have got' belongs to I, you, we and they, and the subject in this gap is the singular 'she'.
• B) has gotCorrect! 'She' is third person singular, so 'have' becomes 'has' while 'got' stays unchanged.
• C) hav gotIncorrect! 'Hav' drops the silent e, and English spelling keeps the full form 'have'.
• D) having gotIncorrect! 'Having got' is the participle form of the perfect, and this sentence describes a permanent state.

Respuesta correcta: B) does

• A) dosIncorrect! 'Dos' is only the third person plural of 'do', and the subject 'he' is singular.
• B) doesCorrect! 'Does' is the third person singular of the irregular verb 'do', used before a base form.
• C) doIncorrect! 'Do' is the bare form, which fits I, you, we and they but not the singular 'he' here.
• D) doingIncorrect! 'Doing' is the -ing form of the progressive, and the simple present of this statement uses no auxiliary.

Respuesta correcta: D) watches

• A) watchsIncorrect! 'Watchs' adds a plain -s after a consonant, but verbs ending in -ch always take -es.
• B) watchIncorrect! 'Watch' is the bare form, and the singular subject 'Maria' requires the third person ending.
• C) watchingIncorrect! 'Watching' is the present participle, and it can only follow the auxiliary 'is'.
• D) watchesCorrect! Verbs ending in -ch take -es in the third person singular, so the form here is 'watches'.

Respuesta correcta: C) don't like

• A) doesn't likeIncorrect! 'Doesn't' is the negative auxiliary of the third person singular, and the subject here is 'I'.
• B) am not likeIncorrect! 'Am not' is the negative of the verb 'to be', and it cannot be followed by 'like'.
• C) don't likeCorrect! With the pronoun 'I' the auxiliary of the negative is 'don't', which never takes an -s.
• D) not likeIncorrect! A negative in the present simple always needs an auxiliary, so 'not like' alone is impossible.

Respuesta correcta: A) isn't

• A) isn'tCorrect! 'Not be' contracts to 'isn't', and that is the negative used with a single subject.
• B) aren'tIncorrect! 'Aren't' is the plural negative of the verb 'to be', and the subject 'he' is singular.
• C) doesn'tIncorrect! 'Doesn't' is the negative of an action verb, and the verb in this gap is 'be'.
• D) don'tIncorrect! 'Don't' is the negative auxiliary of the action verbs, and it does not work with 'to be'.

Respuesta correcta: A) doesn't she

• A) doesn't sheCorrect! The tag takes the negative auxiliary because the main clause is positive, so it reads 'doesn't she'.
• B) isn't sheIncorrect! 'Isn't' belongs to the verb 'to be', and the main clause uses the action verb 'lives'.
• C) don't sheIncorrect! 'Don't' is the auxiliary of I, you, we and they, and it can never follow a third person singular subject.
• D) she doesn'tIncorrect! A tag reverses the order of subject and auxiliary, so 'she doesn't' is not a tag at all.

Respuesta correcta: D) needs

• A) needIncorrect! 'Need' is the bare form, and the singular subject 'every student' requires 'needs'.
• B) needingIncorrect! 'Needing' is the -ing form, which belongs to the progressive after the auxiliary 'is'.
• C) are needIncorrect! 'Are need' mixes a plural auxiliary with a base verb, so two separate rules fail here.
• D) needsCorrect! 'Every student' counts as one singular third person subject, so the verb carries the -s.

Respuesta correcta: B) meets

• A) meetIncorrect! 'Meet' is the bare form, and the singular subject 'the committee' requires 'meets'.
• B) meetsCorrect! 'The committee' is a single third person singular subject, even though its members are many.
• C) meetingIncorrect! 'Meeting' is the participle of the progressive, and the simple present here uses no auxiliary.
• D) meet'sIncorrect! English never writes the third person singular with an apostrophe, so 'meet's' is impossible.

Respuesta correcta: C) doesn't

• A) don'tIncorrect! 'Don't' is the auxiliary of I, you, we and they, and it never carries the third person ending.
• B) isn'tIncorrect! 'Isn't' is the negative of the verb 'to be', and the clause here uses the action verb 'forget'.
• C) doesn'tCorrect! The tag of 'he ...?' takes 'doesn't', which holds the -s of the third person singular.
• D) hasn'tIncorrect! 'Hasn't' would need a past participle after it, and 'forget' in the tag must stay in its base form.
