English

The original direct speech is in present tense: "What a teacher you are!" When converting to indirect speech, the tense shifts back to past tense, so "you are" becomes "he was." Therefore, option B correctly reflects this change.

"Anna Karenina" is a famous novel written by Leo Tolstoy, a renowned Russian author. The other options are poets and playwrights unrelated to this novel.

The analogy compares 'Forecast' to 'Future' as a prediction relates to what is yet to come. Similarly, 'Regret' relates to 'Atone' because regret is feeling sorry for past actions, and to atone is to make amends for them. 'Past' and 'Sins' are related to regret but do not complete the analogy as well as 'Atone'.

The correct article usage is 'The earth moves around the sun.' 'Earth' and 'sun' are unique celestial bodies, so the definite article 'the' is used before both.

The idiom "Hitting the Nail on the Head" means doing something exactly right or performing a task with precision. Option A correctly captures this meaning, while the other options do not reflect the idiomatic usage.

The word 'liaison' means a connection or association between groups or people, so 'Association' is the correct synonym. The other options do not share this meaning.

The phrase "Once in a Blue Moon" is an idiom that means something happens very rarely or infrequently. Therefore, option B, "Rarely," is the correct meaning.

The sentence contrasts a past habitual action with a current situation. 'Rarely comes' (simple present) correctly expresses that he does not visit often now. 'Is rarely coming' is incorrect because 'rarely' does not typically combine with the present continuous. 'Has rarely come' (present perfect) is less appropriate here as the question implies a current habitual state.

The analogy compares the process to the resulting state: 'Melt' results in 'Liquid', so 'Freeze' results in 'Solid'. Therefore, 'Solid' is the correct answer.

The word 'succinct' means expressed in few words, clear and concise. Therefore, 'Concise' is the correct synonym. The other options have opposite or unrelated meanings.

The passive form of the question "Why did you disobey your parents?" is correctly formed as "Why were your parents disobeyed by you?" This is because in passive voice, the object of the active sentence ("your parents") becomes the subject of the passive sentence. The verb "disobey" is changed to its past participle form "disobeyed" and is preceded by the auxiliary verb "were" to match the past tense. The question structure is maintained with "Why" at the beginning. The other options contain grammatical errors such as incorrect verb forms (e.g., "was" instead of "were") or incorrect word order.

The word 'Awfy' is a Scots dialect term meaning 'awful' or 'terrible'. Therefore, the synonym is 'Terrible'.

The word 'bellicose' means demonstrating aggression and willingness to fight, so 'hostile' is the correct synonym among the options provided.

The word 'demur' means to hesitate or show reluctance. Its antonym is 'accept,' which means to agree or consent without hesitation. Therefore, 'accept' is the correct opposite of 'demur.'

The analogy compares an emotion to its typical cause or trigger. Fear is caused by a threat, so anger is caused by provocation. Psychological and legal research supports that anger is typically triggered by provocation or insult, while fear is triggered by threat or danger. Among the options, 'Provocation' is the most accurate and direct cause of anger, making C the best answer. 'Force' can provoke anger but is less precise than 'Provocation' in this analogy context.

The analogy compares pairs of related economic terms. 'Import' and 'Export' are complementary activities representing goods coming into and going out of a country, respectively. Similarly, 'Expenditure' and 'Revenue' are complementary financial terms representing money going out and money coming in, respectively. 'Deficit' is a consequence of expenditure exceeding revenue, not a direct counterpart. Therefore, the best analogy is Import : Export :: Expenditure : Revenue.

An appraiser evaluates a building, similarly, a critic evaluates a masterpiece. Thus, the correct analogy is 'Critic : Masterpiece'.

The analogy compares a gemstone to its characteristic color: Ruby is red, and similarly, Sapphire is blue. Thus, the correct answer is Blue.

The analogy compares a cause to its effect or consequence. Fog causes reduced visibility, similarly, AIDS often leads to death. Therefore, 'Death' is the correct analogous pair to 'Visibility' in the context of 'Fog'.

The analogy compares 'Command' to 'Order' as 'Confusion' relates to 'Chaos'. Command leads to order, while confusion leads to chaos, making option C the correct choice.

The analogy compares capital cities to their respective countries. Tehran is the capital of Iran, so Beijing is the capital of China, making option A correct.

The analogy compares a porcupine to a rodent, identifying the category or classification of the first word. Similarly, mildew is classified as a fungus, making 'Fungus' the correct answer.

The analogy compares pairs of related actions: 'Push' is related to 'Pull' as opposite or complementary actions, and similarly, 'Throw' is related to 'Pick' as opposite or complementary actions involving handling objects.

An oven produces heat, so the analogous item that produces cold is an air conditioner. While ice cream and snow are cold, they are not devices or sources that create cold like an oven creates heat. A refrigerator also produces cold but is more for storage, whereas an air conditioner actively cools the environment, making it the best analogy.

Myopia is a disease or disorder related to the eye, so the analogy asks for a disease related to teeth. Pyorrhoea is a dental disease, making it the correct answer.
