English

A 'truce' is a temporary cessation of fighting, and 'armistice' specifically refers to an agreement to stop hostilities, making it the best synonym among the options. While 'agreement' and 'settlement' are related, they are broader terms and less precise in this context. 'Ratify' means to formally approve, which is not a synonym.

The term 'Aborigines' specifically refers to the original inhabitants of a country, especially used in contexts like Australia. However, 'Natives' is a more general and widely accepted term for the original inhabitants of any country or region. 'Aborigines' is often considered specific to certain groups, such as the Indigenous peoples of Australia, and can sometimes be seen as outdated or offensive in some contexts. 'Citizens' refers to legal members of a country, and 'Primitive' is an outdated and inappropriate term. Therefore, the most accurate and general answer to the question 'Who are the original inhabitants of a country?' is 'Natives.'

The word 'torture' means severe physical or mental pain inflicted on someone. The antonym is 'peace,' which means a state of tranquility or absence of pain and suffering, making option C the correct opposite.

The correct future perfect tense is 'will have begun' to indicate that the play will start before he arrives. 'Would have begun' and 'would begun' are incorrect forms, and 'will begun' is grammatically wrong.

The correct preposition to complete the phrase 'What is the cause ___ the problem?' is 'of'. The phrase 'cause of the problem' is the standard and grammatically correct expression in English.

The correct preposition to use with 'interested' when referring to a subject is 'in'. Therefore, 'He is interested in history?' is correct.

"Retaliation" means to respond to an injury or wrong by inflicting harm in return, which is synonymous with "Revenge." The other options do not convey this meaning.

The correct phrase is 'Her talking so much' because it correctly uses the possessive pronoun 'her' followed by the gerund 'talking' to function as a noun phrase, which fits the sentence structure after 'there no reason for'.

A large group of birds flying together, especially starlings, is called a 'murmuration.' 'Startling' is incorrect; the correct term is 'starling' for the bird species, not the group. Therefore, option B is correct.

The phrase 'rank and file' refers to the ordinary members or the general body of an organization, especially excluding the leaders or officers. Therefore, option A correctly defines 'rank and file' as 'The ordinary members.'
