In the following sentence, choose the alternative that best improves the bracketed part. It is one thing for adultery to get you a divorce and (quite some other) for it to lead you to incarceration.

Introduction / Context:
This sentence examines a legal or moral distinction between adultery as a ground for divorce and as a ground for imprisonment. The bracketed phrase "(quite some other)" is awkward and non idiomatic. We must choose the correct fixed expression that contrasts two situations: "It is one thing ... and quite another ...". Such idiomatic structures are often tested in English improvement questions.

Given Data / Assumptions:

• The structure "It is one thing ... and ..." normally takes "quite another" in the second part.
• The bracketed expression "quite some other" is non standard.
• The options are:
  • quite another
  • quite any other
  • quite every other
  • No improvement
• The intended meaning is that getting a divorce is one type of consequence, while going to prison is a completely different and more serious consequence.

Concept / Approach:
We rely on knowledge of idioms and fixed patterns:

• The pattern "It is one thing to do X and (quite) another (to do Y)" is standard English.
• Words like "any other" or "every other" do not fit this idiomatic construction.
• A non standard variant such as "quite some other" should be rejected even if it seems roughly meaningful.

Step-by-Step Solution:
Step 1: Recognise the structure "It is one thing ... and ..." and recall that the correct completion is "quite another". Step 2: Option A "quite another" exactly matches this pattern: "It is one thing for adultery to get you a divorce and quite another for it to lead you to incarceration." Step 3: Option B "quite any other" is ungrammatical in this pattern and does not form a known idiom. Step 4: Option C "quite every other" is also wrong; it suggests comparison with every other thing rather than one specific contrasting situation. Step 5: The original "quite some other" is not idiomatic, so "No improvement" is not acceptable. Step 6: Therefore, the best improvement is "quite another".

Verification / Alternative check:
Insert the correct option into the full sentence: It is one thing for adultery to get you a divorce and quite another for it to lead you to incarceration. This is a clear, natural sentence that emphasises the difference between civil consequences (divorce) and criminal consequences (imprisonment). All other options sound forced or incorrect and would not appear in formal writing.

Why Other Options Are Wrong:

• quite any other: Does not fit the structure "It is one thing ... and quite any other ...", which is not an English idiom.
• quite every other: Suggests something like "every other thing", which is not what the sentence intends.
• No improvement: Retains the non idiomatic phrase "quite some other".

Common Pitfalls:
Many candidates fail to recognise that some structures in English are fixed collocations and are not flexible. They may try to improvise with "any other" or "some other" without realising that these break the idiom. It is useful to learn common patterns such as "on the one hand ... on the other hand" and "It is one thing ... and quite another" because they appear frequently in exams and formal writing.

Final Answer:
The correct improved phrase is quite another, so the correct option is "quite another".
