English

A 'paragon' is a model of excellence or perfection, so 'Model' is the correct synonym. 'Virtue' refers to moral excellence but is not a direct synonym, 'Square' is unrelated, and 'None' is not an appropriate choice.

The prefix 'un-' is used to form the opposite of 'believable,' making 'unbelievable' the correct word to complete the sentence. 'In-' and 'dis-' are prefixes but do not correctly form the opposite of 'believable' in this context. 'None' is not a prefix and is incorrect.

The word 'exemplify' means to illustrate or clarify by giving an example, making 'Illustrate' the correct synonym. The other options do not share this meaning.

The word 'gainsay' means to deny, contradict, or oppose something. Among the options, 'Oppose' is the closest synonym, making it the correct answer.

Option C is grammatically correct because 'footsteps' is plural, so the verb must be 'are heard' to agree in number. The sentence is also in the present tense, matching 'when I am alone.'

In conditional sentences of the first type, the present simple tense is used in the 'if' clause to indicate a possible future event. Therefore, 'If I win the match' is correct. 'I will win' and 'I shall win' are future tense and not used in the 'if' clause; 'I wins' is grammatically incorrect.

The antonym of 'abridge' (which means to shorten or condense) is 'elaborate,' meaning to expand or add detail. While 'augment' means to increase, it is less precise as an antonym in this context than 'elaborate.'

The correct idiomatic expression is 'jump to the conclusion' or more commonly 'jump to conclusions' (plural). This phrase means to make a decision or form an opinion hastily without having all the facts. The preposition 'to' is standard in this idiom, while 'jump on the conclusion' is not idiomatic English. Therefore, the correct answer is B: 'To'.

The word "chaste" means pure or abstaining from sexual activity, so its antonym is "promiscuous," which means having many sexual partners. The other options do not relate to the meaning of "chaste."

The correct preposition to use with 'famous' in this context is 'for,' as it indicates the reason for fame or recognition. Therefore, 'I am famous for honesty' is correct.
