English

The word 'Karachi' is a proper noun because it is the specific name of a city. Proper nouns always begin with a capital letter and name particular people, places, or things.

The original sentence is "I bought it of my own accord." The correct phrase is "of my own accord," but the options A, B, and C contain errors such as "if" instead of "it," "of you own acccord" (misspelled), and incorrect pronouns and verbs. Therefore, none of the options correctly represent the sentence, making D the correct choice.

The correct phrase is 'A believer smiles in public and weeps in private.' 'Weeps' is the correct verb form to parallel 'smiles' and convey the intended meaning. The other options are grammatically incorrect or inappropriate.

The word 'Clime' means a region considered with reference to its climate. None of the given options correctly define 'Clime', so the correct answer is 'None of these'.

The 'Inside address' section of a formal letter contains the receiver's address. It is placed below the sender's address and date, before the salutation.

The correct preposition to use with 'yearned' in this context is 'for', as in 'yearned for the return to her own home.' This expresses a strong desire or longing for something.

The sentence "Let me do this." is a direct offer or request by the speaker to perform a task. It conveys willingness and initiative to take responsibility for the action. The best paraphrase would be something like "Allow me to handle this" or "I will do this." Option A, "Let this be done by me," changes the sentence to passive voice and alters the tone and immediacy of the original. Options B and C also do not accurately convey the meaning. Therefore, none of the given options A, B, or C correctly paraphrase the sentence, making option D (None of these) the correct choice.

A compound noun is a noun made up of two or more words that function as a single noun. 'Love-fest' is a compound noun formed by combining 'love' and 'fest'. The other options are either adjectives or single nouns, not compound nouns.

The correct preposition to indicate a time limit is "within," meaning the homework must be finished inside the two-hour period. The other options do not correctly convey this meaning.

Some verbs require a complement to complete their meaning and make the sentence grammatically correct. A complement provides necessary information about the subject or object, which is why 'Complement' is the correct choice.
