English Language Proficiency - Vocabulary and Grammar

The sentence 'The horse raced past the barn fell jumped' is ungrammatical because it contains too many verbs. The correct garden-path structure would be 'The horse raced past the barn fell' (one verb too many). The other options are valid grammatical sentences.

The correct answer is 'I had sent the mail yesterday.' The original sentence incorrectly uses the base form 'send' with the past perfect auxiliary 'had.' Past perfect requires the past participle form 'sent.' Option B incorrectly uses 'have send' (present perfect with base form), Option C incorrectly uses simple present 'send' for a past action, and Option D 'have sent' is grammatically correct present perfect but doesn't match the past perfect structure of the original sentence.

The subject 'She' is third-person singular, so in simple present tense the verb must end with -s. 'She takes' is grammatically correct. 'She has taken' is present perfect tense (also grammatically correct), but the question stem 'She take' is simple present, so 'She takes' is the direct correction. 'She have taken' incorrectly uses 'have' with a singular subject.

The negative of 'do' in third-person singular is 'does not' or 'doesn't'. The original sentence 'He don't come' incorrectly uses 'don't' with a singular subject. 'He doesn't come' is the grammatically correct negative present tense form. 'He didn't come' is past tense, and 'He won't come' is future.

Both 'I am not able to' and 'I am unable to' are grammatically correct ways to express inability. 'Unable' is the direct negative of 'able', while 'not able' uses the negation. Options C and D incorrectly use 'able' with 'didn't' and 'won't' - it should be 'wasn't able to' and 'won't be able to'.

With 'neither/nor', the verb agrees with the subject closest to it. Here, 'I' is closest, so we need 'was' (first person singular). Also, 'neither/nor' is the correct correlative conjunction pair, not 'neither/or'.

The sentence 'She does not knows you' is incorrect. After the auxiliary 'does', we use the base form of the verb, not the third person singular form. It should be 'She does not know you' or 'She doesn't know you'.

The question 'Why don't he come to work in time?' has two errors. First, with 'he', we should use 'doesn't', not 'don't'. Second, in questions about habitual actions, we typically use present tense with 'do' - 'Why doesn't he come' is correct for present habitual, or 'Why didn't he come' for past specific.

The subject The doctor is singular, so it requires the singular verb form has examined instead of have examined. Therefore, the sentence is incorrect, making False the correct answer.

The sentence 'I am working since morning' is incorrect. With 'since' (indicating a starting point), we use the present perfect continuous: 'I have been working since morning'. The present continuous 'am working' requires 'for' or 'since' with different time reference, or simply 'I started working in the morning'.

The sentence 'I can able to fix your problem' is incorrect. 'Can' and 'able to' both express ability and cannot be used together. Correct forms are 'I can fix your problem' or 'I am able to fix your problem'.

The sentence 'I did not talk to the customer' is grammatically correct. 'Did not talked' would be wrong because after the auxiliary 'did', we use the base form of the verb. The sentence correctly uses simple past tense negation.

Matutinal comes from Latin 'matutinus' meaning 'of the morning'. It refers to something occurring or relating to the morning, or early morning hours. The word is related to 'matins' (morning prayers).

Convivial comes from Latin 'convivium' meaning 'feast' or 'banquet'. It describes someone who is sociable, fond of feasting and good company, or relates to social gatherings with food and drink. It doesn't mean merely friendly (that's 'congenial'), but specifically merry and festive in social contexts.

Fractious describes someone who is troublesome, unruly, or inclined to cause trouble and quarrels. It comes from 'fraction' (breaking into parts) - a fractious person breaks harmony. It doesn't mean 'relating to fracture' (that's medical) or 'raspy' (that's describing a sound).

Phantasmagoria refers to a dreamlike sequence of images or things seen, like a shifting dream vision. It comes from Greek 'phantasma' (illusion, phantom) and 'agora' (assembly/place). It describes a bizarre, changing series of things seen or imagined, not specifically a mental disorder or opium delirium (though it can describe such visions).
