B. them. That is the unacceptable word in the sentence.
This is an external conflict. An external conflict happens between a character, in this case the employee, and some external obstacle or challenge. This challenge can be a person, animal, thing, or something a bit more abstract like a deadline.
An internal conflict, on the other hand, is between the character and his or herself, perhaps due to opposing values or goals. In this case, the employee might be conflicted between working on the deadline or just quitting her job and moving to Bora Bora (she should choose the second one)
Answer: answer is A/ segregation
Explanation:
In the first question, the answer is - D. A - cannot be the correct answer as common nouns (such as - chair, computer, desk) don't have to be written in capital letters. And regarding B, proper nouns (such as John, Thames. America) always have to begin with a capital letter. C - is simply incorrect, using proper nouns, that is, names, isn't more polite than saying, for example, a wall.
Regarding the second question, the answer is - B. It is the only sentence in which the past simple tense of the verb "to bring" is used. The first example uses the present perfect tense (which isn't a past tense), C - present continuous, and D - future simple.
