CAN SOMEONE PLEASE HELP WITH THIS

None of the words you posted fit into this analogy.

To find the answer to this analogy, we need to identify the relationship between "beginning" and "end". "Beginning" refers to the start or the first part of something, while "end" refers to the conclusion or the last part. The relationship here is one of sequence or progression.

Now we can apply this same relationship to the second pair of words, "greeting" and an unknown word. A "greeting" is an act of acknowledging someone or expressing welcome. To find the word that is related to "greeting" in the same way as "end" is related to "beginning," we need to think about what comes after or is related to a greeting in a sequential or progressive sense.

The word that fits this analogy would be "farewell". A "farewell" is the act of saying goodbye to someone, which is the counterpart to the initial greeting. Just as "beginning" is to "end," "greeting" is to "farewell". So, the answer is "farewell".
