1. What We're Solving

We need to find the right word to complete: "Who doesn't respect him ________ knows how much he has sacrificed for the country?"

---

2. The Approach

The key is to understand the sentence's overall structure first before deciding which connector belongs in the blank. Ask yourself:

• What is the main clause?
• What is the subordinate/relative clause?
• What does the blank word need to do grammatically?

---

3. Step-by-Step Solution

Step 1: Read the sentence as a whole

> "Who doesn't respect him ________ knows how much he has sacrificed?"

This sentence has an unusual structure — it's a rhetorical question with a very specific form.

---

Step 2: Identify the meaning

The intended meaning is: > "Nobody who knows how much he sacrificed doesn't respect him."

Or more naturally: > ✅ "Who doesn't respect him but knows how much he sacrificed?"

This is a rhetorical question meaning: "Anyone who knows his sacrifices MUST respect him."

---

Step 3: Test the student's answer — `that`

You suggested rearranging as: > "Who that knows how much he sacrificed doesn't respect him?"

Here's the problem with `that` as a relative pronoun in this position:

> ❌ In English, `that` cannot follow `who` directly when `who` is an interrogative pronoun (a question word).

We say:

• ✅ "The person that knows..." (that follows a noun)
• ❌ "Who that knows..." (that cannot follow an interrogative `who`)

`That` needs a noun antecedent — but `who` here is a question word, not a noun!

---

Step 4: Test option `but`

The word `but` has a special grammatical function that students often overlook. In formal or literary English, `but` can act as a relative pronoun meaning "who/that...not" or "except one who."

Classic examples: > - "There is nobody but loves their homeland." → Nobody who doesn't love their homeland > - "There is no rule but has exceptions." → No rule that doesn't have exceptions

So our sentence becomes: > "Who doesn't respect him but [= who] knows how much he has sacrificed?"

Meaning: "Anyone who knows his sacrifices cannot fail to respect him." ✅

This is grammatically correct and stylistically consistent with formal/literary English!

---

Step 5: Why not the others?

| Option | Problem | |--------|---------| | A. that | ❌ Cannot follow interrogative `who` | | B. who | ❌ Creates two separate clauses awkwardly — "who knows" would just repeat the subject without the right logical connection | | C. / (nothing) | ❌ The sentence needs a connector for the meaning to work | | D. but | ✅ Functions as a relative pronoun meaning "who...not / except who" |

---

4. The Answer

✅ D. `but`

The complete sentence: > "Who doesn't respect him but knows how much he has sacrificed for the country?"

`But` here is a literary/formal relative pronoun meaning "who at the same time" or "and yet who," making this a rhetorical question implying everyone who knows respects him.

---

5. Memory Tip 💡

> "BUT can be a secret relative pronoun!" > Think of the phrase "None but the brave deserve the fair" — `but` = `who...not` / `except who` > > A quick test: If you can replace the blank with "who at the same time" and the meaning holds → `but` is your word! 🎯

Your instinct to analyze clause structure was on the right track. The tricky part here is recognizing `but` in its rare relative pronoun role, which appears mostly in formal and literary contexts. Great question! 🌟
