Coordinating Conjunctions worksheet with fill-in-the-blank exercises and a cute cow illustration.

Explanation:
We are given a worksheet about coordinating conjunctions. The two options to choose from are: and and unless.

Let’s recall what each means:
- and = used to join two ideas that both happen or are both true (adds something).
- unless = means “if not” — it introduces a condition; the first part happens *only if* the second part does *not* happen.

Now go sentence by sentence and decide which word fits best.

1. *The cow won’t be happy ________ you’ll be my valentine.*
→ The cow is unhappy *unless* you become the valentine. So: unless

2. *We will be late ________ we don’t hurry.*
→ We will be late *if* we don’t hurry → same as *unless* we do hurry. But the blank comes before “we don’t hurry”, so: unless
(We will be late unless we hurry → but here it says “unless we don’t hurry”? Wait — let’s re-read.)
Actually: “We will be late ________ we don’t hurry.”
If we don’t hurry → we will be late. So the condition for being late is *not hurrying*. That means:
We will be late if we don’t hurry. But “if” isn’t an option — only and or unless.
Can we use unless?
“We will be late unless we don’t hurry” would mean: we will be late *except when* we don’t hurry — which is nonsense.
So that can’t be. Let’s test and:
“We will be late and we don’t hurry” — that’s two statements, but doesn’t show cause. Not ideal.
Wait — maybe the intended logic is:
We will be late unless we hurry. But the sentence says “we don’t hurry”, so perhaps there’s a mistake in our reading.

Let me double-check the sentence:
> 2. We will be late ________ we don’t hurry.

This is a classic structure:
“We will be late unless we hurry.”
But here it says “we don’t hurry”, so to make sense with unless, we’d need to flip it.

Actually, think logically:
- “Unless X” = “if not X”
So: “We will be late unless we hurry” = “We will be late if we do not hurry”.
That matches the sentence: “We will be late [unless we hurry]” → which implies the condition is *hurrying*. But the sentence gives “we don’t hurry” after the blank.

Wait — the blank is *before* “we don’t hurry”, so:
“We will be late ________ we don’t hurry.”
If we fill unless:
→ “We will be late unless we don’t hurry.”
That means: we will be late except when we don’t hurry → i.e., we’re only on time when we *don’t* hurry — which is backwards.

So unless doesn’t work here. Try and:
“We will be late and we don’t hurry.”
That’s grammatical but odd — it states two facts, not a condition.

Hold on — maybe the worksheet expects unless in most cases, and this one is tricky. Let’s look at other sentences to see the pattern.

3. *I will call you ________ you give me your number.*
→ I will call you if you give me your number. Again, “if” not available.
But “unless” would give: “I will call you unless you give me your number” → meaning I won’t call you if you give it — opposite of intent.
So likely and? “I will call you and you give me your number” — still awkward.

Wait — maybe we misread the instruction. It says:
> Choose from the conjunctions if and unless

But the header says: “Choose from the conjunctions and unless” — looking back:
In the user message, it says:
“Choose from the conjunctions if and unless” — but in the image description, it says “and unless”.

Let me re-read the original prompt:
> Choose from the conjunctions if and unless to fill in the blank...

Actually, the user wrote:
"Choose from the conjunctions if and unless" — but in the image text (as transcribed), it says:
"Choose from the conjunctions if and unless" — no, the transcribed text says:
"Choose from the conjunctions if and unless" — wait, in the problem statement above, it says:

> Choose from the conjunctions if and unless to fill in the blank in each sentence below.

But in the very first line of the worksheet in the transcription, it says:
"Choose from the conjunctions if and unless"

However, in the user’s message, the line is:
"Choose from the conjunctions if and unless" — yes.

But in the initial system prompt, it says:
“The user uploaded an image containing a task.” and then the transcription shows:
"Choose from the conjunctions if and unless"

Wait — looking carefully at the transcribed worksheet:

> Choose from the conjunctions if and unless to fill in the blank in each sentence below.

Yes! So the options are if and unless, *not* “and” and “unless”. The earlier mention of “and” was a misread.

That changes everything.

So options: if and unless

Recall:
- if = condition: X happens *in case* Y happens.
- unless = *except if* / *if not*: X happens *only when* Y does not happen.

Now re-solve:

1. *The cow won’t be happy ________ you’ll be my valentine.*
→ Cow is unhappy unless you are valentine. So: unless

2. *We will be late ________ we don’t hurry.*
→ We will be late if we don’t hurry. ✔ So: if

3. *I will call you ________ you give me your number.*
→ I will call you if you give me your number. ✔ if

4. *We won’t succeed ________ we work together.*
→ We won’t succeed unless we work together. (i.e., we succeed only if we work together)
So: unless

5. *I will be tired ________ I don’t get to sleep early.*
→ I will be tired if I don’t get to sleep early. ✔ if

6. *I won’t come over ________ you say it’s OK.*
→ I won’t come over unless you say it’s OK. (I’ll come only if you approve)
So: unless

7. *I won’t take a shower ________ there is hot water.*
→ I won’t take a shower unless there is hot water. (I’ll shower only if hot water exists)
So: unless

8. *I will say I don’t remember this ________ you ask me later.*
→ I will say I don’t remember this if you ask me later. (Condition: when you ask)
So: if

9. *You won’t succeed ________ you keep trying.*
→ You won’t succeed unless you keep trying. (Success requires trying)
So: unless

10. *He will remember you ________ you tell him that story.*
→ He will remember you if you tell him that story. ✔ if

11. *The dog will behave ________ you train him.*
→ The dog will behave if you train him. (Training leads to good behavior)
Could also be “unless you train him, he won’t behave”, but the sentence is positive: “will behave ___ you train him” → natural fit is if

12. *I don’t go out ________ I have to.*
→ I don’t go out unless I have to. (I only go out when necessary)
So: unless

Now list all answers:

1. unless
2. if
3. if
4. unless
5. if
6. unless
7. unless
8. if
9. unless
10. if
11. if
12. unless

Double-check #11:
“The dog will behave ________ you train him.”
If we put *unless*: “The dog will behave unless you train him” → means dog behaves *only when you don’t train* — wrong.
So if is correct.

All consistent.

Final Answer:
1. unless
2. if
3. if
4. unless
5. if
6. unless
7. unless
8. if
9. unless
10. if
11. if
12. unless
