Scientific facts, universal truths, and laws of nature use the simple present tense because they are always true. "The earth revolves around the Sun" is a universal fact.

"Either" is always singular, so it takes a singular verb. "Either of the applicants was" is correct because either refers to one individual, not both.

The subject is "The house" (singular), not "contents." The phrase "with its contents" is parenthetical and doesn't affect the verb. So "is insured" is correct.

The moon moves around the earth is a general truth or regular occurrence. Present simple tense (moves) is used for universal facts and habitual actions. Option A (move) is incorrect because 'moon' is singular. Option C (moved) is past tense, and Option D (has been moving) suggests an ongoing action which doesn't fit a general truth.

When 'He and I' forms a compound subject, it requires the plural verb 'are'. This follows the subject-verb agreement rule where compound subjects joined by 'and' take plural verbs. Options A (is) and B (am) are singular, while Option D (have) is the wrong auxiliary verb for continuous tense.

'Bread and butter' is treated as a singular concept when referring to a single dish or means of sustenance, so it takes the singular verb 'is'. This is an exception where a phrase joined by 'and' acts as a singular unit. Options B (am) and C (are) are incorrect subject-verb combinations, while D (have) is the wrong verb entirely.

The correct preposition is 'to' - we say something is 'opposite to' something else. This is a fixed collocation in English. Options A (of), C (for), and D (with) don't form the correct prepositional phrase with 'opposite' in this context.

Amounts of money and measurements are treated as singular concepts in English, requiring the singular verb 'is'. One hundred paisa is considered a single unit of value. Options B (am) and C (are) are incorrect subject-verb combinations, while D (have) is the wrong verb.

'His means' refers to his resources or income, which is treated as plural in English, requiring 'are'. This is a fixed usage where 'means' as a noun (meaning resources/wealth) always takes a plural verb. Options A (is) and B (am) are singular, while D (have) is the wrong auxiliary verb.

'According to' is the correct phrase meaning 'in accordance with' or 'following'. Option A is grammatically correct. Option B ('according') is incomplete, while Option C ('as according') is redundant and incorrect.

This is a hypothetical conditional statement using the subjunctive mood. 'If I were' is the correct form for counterfactual or hypothetical situations, even though 'I' normally takes 'am'. Options A (is), B (am), and C (are) don't use the subjunctive 'were' required for this hypothetical structure.

The sentence requires the simple past tense 'advised' to match the context of a completed action. Option D is correct. Option A ('inform') is present tense, Option B ('advice') is a noun not a verb, and Option C ('adviced') is not a valid word (advise → advised).

The sentence indicates current possession, requiring the present simple 'has' for the third person singular subject 'He'. Option B is correct. Option A ('have') is for first/second person or plurals, Option C ('having') is a participle, and Option D ('will have') is future tense.

The correct preposition is 'from' - we derive something 'from' a source. This is standard usage when indicating origin or source. Options A (of), B (in), and D (to) don't correctly show the source-relationship in this context.

When a relative pronoun follows a preposition ('of'), we must use 'whom' instead of 'who'. 'Whom' is the object case, required after prepositions. Options A (what), B (who), and D don't correctly fill this grammatical position.
