This question asks us to choose the correct pair of homophones to complete the given sentence. Homophones are words that sound the same but have different spellings and meanings. We need to understand the meaning of the words provided in the options to use them correctly in the context of the sentence.

The options involve the words "altar" and "alter". Let's look at their meanings:

• Altar: A table or flat-topped block used as the focus for a religious ritual, especially for making sacrifices or offerings. In Christianity, it is a table or structure used for the sacrament of the Eucharist. It is usually found in a church.
• Alter: To change or make different; to modify.

Now let's examine the sentence:

"The pastor called those needing prayer to come to kneel at the church’s ________. The man who is constantly making decisions and being compelled to ________ those gets nowhere."

Let's analyze each blank:

• First blank: "kneel at the church’s ________". The context is a church and kneeling for prayer. The word that fits this religious context is "altar". People kneel at the altar in a church during prayer or service.
• Second blank: "being compelled to ________ those gets nowhere". This phrase talks about making decisions and being compelled to do something to "those" (presumably decisions or actions). The word needed here means to change or modify decisions. The word that means to change is "alter". If someone is always compelled to "alter" their decisions (change them), they won't make progress or "get anywhere".

Based on this analysis, the correct pair of words to fill the blanks is "altar" for the first blank and "alter" for the second blank.

Let's check the options:

1. altar; altar - Incorrect. The second blank requires "alter" (to change), not "altar" (church structure).
2. altar; alter - Correct. "Altar" fits the church context, and "alter" fits the context of changing decisions.
3. alter; alter - Incorrect. The first blank requires "altar" (church structure), not "alter" (to change).
4. alter, altar - Incorrect. The first blank requires "altar", and the second blank requires "alter". The order is reversed here.

Therefore, the correct pair of homophones is "altar; alter".
