The word "accord" as a noun or verb often means to grant or give something, such as rights or status. Therefore, "grant" is the correct synonym among the options provided.

The word "contiguous" means sharing a common border or being very close to something. "Proximate" means near or close, making it the correct synonym. The other options mean distant or unrelated, which are antonyms or unrelated terms.

The phrase 'either in flat or shared house' correctly fits the sentence as it indicates a choice between two options. 'Either' is used to refer to one or the other of two things, which is appropriate here.

The subject of the sentence is 'Maryam,' which is singular. The phrase 'accompanied by her brother' is a non-essential modifier and does not change the number of the subject. Therefore, the verb must agree with the singular subject 'Maryam.' The correct verb form is the singular present tense 'is.' The original answer 'was' is incorrect because the sentence is in the present tense and the subject is singular. Hence, the correct sentence is 'Maryam, accompanied by her brother, is at the party.'

The word "supplant" means to replace or displace someone or something, making option C, "displace," the correct synonym. The other options do not convey this meaning.

The word 'declaim' means to speak loudly and with strong emotion, often in a dramatic or formal manner. Therefore, the synonym 'speak dramatically' (option D) is the correct choice. 'Denounce' means to publicly condemn, which is different in meaning.

The word "benchmark" means a standard or reference point against which things may be compared or assessed. Among the options, "reference point" is the closest synonym, making option B correct.

The word 'abrade' means to wear away or scrape off the surface by friction. Therefore, 'wear away' is the correct synonym among the options provided.

The word "succulent" primarily means juicy or rich in moisture, often used to describe food or plants that are thick and fleshy. Common synonyms include juicy, moist, luscious, and rich. The options given (asking help, wicked, anxious, concise) do not include any true synonyms of "succulent." Among the options, none are correct synonyms. The original answer "D" (concise) is incorrect as "succulent" does not mean concise. Since none of the options are synonyms of "succulent," the question options are flawed. However, based on the options provided, none is correct. The correct synonym for "succulent" would be words like "juicy" or "moist," which are not listed. Therefore, the question should be revised to include appropriate synonyms. For now, the correct answer cannot be any of the given options.

The word 'abut' means to be adjacent to or to border on something. Therefore, 'border on' is the correct synonym among the options provided.
