Worksheet on using correlative conjunctions like "both...and," "either...or," and "not only...but also" to complete sentences correctly.

Let’s go through each sentence one by one. We’ll pick the best pair of correlative conjunctions from the box:
either...or, both...and, not only...but also, neither...nor

---

1. Mediation ______ impresses focus ______ enhances memory.
→ This means mediation does TWO good things — it impresses focus AND enhances memory.
✔ Best fit: not only...but also
→ “Mediation not only impresses focus but also enhances memory.”

---

2. ______ Mia ______ Max would drive the car.
→ Only ONE of them will drive — not both, not neither. It’s a choice between two.
✔ Best fit: Either...or
→ “Either Mia or Max would drive the car.”

---

3. Jack was ______ quick ______ in solving the puzzle.
→ Again, this is saying Jack did something well — he was fast AND accurate (implied).
✔ Best fit: not only...but also
→ “Jack was not only quick but also in solving the puzzle.” *(Wait — that sounds off. Let’s check grammar.)*
Actually, “quick” is an adjective, and “in solving the puzzle” is a phrase. Maybe it should be:
“Jack was not only quick but also clever in solving the puzzle?” But the blank is just for the conjunctions.
Looking again — maybe it’s meant to be:
“Jack was not only quick but also accurate...” — but we don’t have “accurate”.
Wait — perhaps the second part is missing a word? But based on what’s given, “not only...but also” still fits best if we assume the second part implies another quality.
Alternatively, maybe it’s “both...and”?
“Jack was both quick and [good] in solving the puzzle.” Still awkward.
But looking at common usage — “not only...but also” is used to add emphasis to two qualities.
I think the intended answer is not only...but also, even if the sentence feels incomplete.
Let’s move on and come back.

Actually — let’s re-read: “Jack was ______ quick ______ in solving the puzzle.”
Maybe it’s supposed to be: “Jack was not only quick but also skilled in solving the puzzle.”
Since we can only choose from the pairs, and “not only...but also” adds extra info, I’ll stick with that.

BUT — wait! There’s another possibility: “both...and” could work if we interpret it as “Jack was both quick and effective in solving the puzzle.”
Hmm. Actually, “both...and” connects two equal parts. “Quick” is an adjective, “in solving the puzzle” is a prepositional phrase — they’re not parallel.
So “not only...but also” is better because it can connect different structures sometimes.
Still, let’s look at other sentences first.

4. ______ Ethan ______ Evan was invited to the wedding.
→ The verb is “was” — singular. That means only ONE person was invited.
If it were “were”, it might be “both...and”. But “was” suggests only one.
Also, the context doesn’t say both were invited — so likely only one.
✔ Best fit: Either...or
→ “Either Ethan or Evan was invited to the wedding.” → Makes sense with “was”.

Wait — but “either...or” usually takes plural verb if subjects are plural? No — actually, when using “either...or”, the verb agrees with the subject closer to it. Here, “Evan” is singular, so “was” is correct.
Yes, “Either...or” works.

But let’s consider: if BOTH were invited, it would be “Both Ethan and Evan were invited.” But here it says “was”, so probably only one.
So yes — Either...or

5. That was ______ an inspirational speech ______ everyone listened with great attention.
→ This is showing cause and effect — the speech was so good THAT everyone listened.
But our options don’t include “so...that”. Wait — do they?
Looking back at the box: either...or, both...and, not only...but also, neither...nor
None of these directly show result.
But “not only...but also” can sometimes imply addition, not result.
Wait — maybe it’s “so...that” but that’s not in the box.
Hold on — perhaps I misread. Let me check the original image description again.

In the user’s message, the box says:
Correlative conjunctions: either...or, both...and, not only...but also, neither...nor

No “so...that”. So we must use one of these four.

How about: “That was not only an inspirational speech but also [something else]”? But the second part is “everyone listened...” which is a clause, not a noun phrase.

This is tricky. Maybe it’s “both...and”?
“That was both an inspirational speech and everyone listened...” — no, that doesn’t make sense grammatically.

Perhaps it’s a mistake, or perhaps we need to think differently.

Another idea: maybe it’s “not only...but also” implying that the speech was inspiring AND caused people to listen.
Even though it’s not perfect, it’s the closest.

But let’s skip and come back.

6. The test was ______ difficult ______ challenging — but I thought of my success all the way through.
→ “Difficult” and “challenging” are similar — so it’s emphasizing that it was very hard.
We want to say it was BOTH difficult AND challenging.
✔ Best fit: both...and
→ “The test was both difficult and challenging”

Perfect.

7. The bus will leave on time ______ we reach ______ not.
→ This is saying: whether we reach or not, the bus leaves on time.
It’s presenting two possibilities: we reach OR we don’t reach.
✔ Best fit: whether...or — but that’s not in the box!
Our options are: either...or, both...and, not only...but also, neither...nor

“Either...or” could work: “The bus will leave on time either we reach or not.” — but that’s not standard. Usually it’s “whether...or”.

Wait — perhaps it’s “whether...or” but since it’s not listed, maybe the intended answer is “either...or”, even though it’s not ideal.

Actually, in some contexts, “either...or” can be used like this, but it’s rare.

Another thought: maybe it’s “regardless of whether”, but again, not in options.

Let’s look at the structure: “on time ______ we reach ______ not” — the blanks are for the conjunctions.

Perhaps it’s “whether...or”, but since it’s not available, maybe the worksheet has a typo, or perhaps I missed something.

Wait — in the initial box, is “whether...or” included? Let me double-check the user’s input.

User said:
“Correlative conjunctions: either...or, both...and, not only...but also, neither...nor”

No “whether...or”. So we must choose from these.

“Neither...nor” would mean: “The bus will leave on time neither we reach nor not.” — that doesn’t make sense.

“Both...and” — “both we reach and not” — nonsense.

“Not only...but also” — “not only we reach but also not” — no.

So only “either...or” is possible, even if awkward.

Perhaps the sentence is: “The bus will leave on time whether we reach or not.” — but since “whether” isn’t an option, maybe the intended answer is “either...or”, accepting the slight grammatical stretch.

I think for school level, they might expect “either...or” here.

8. The animal shelters are ______ safe ______ clean.
→ This is describing two positive qualities of the shelters.
✔ Best fit: both...and
→ “The animal shelters are both safe and clean.”

Perfect.

Now let’s go back to sentence 3 and 5.

Sentence 3: “Jack was ______ quick ______ in solving the puzzle.”
After thinking, I recall that “not only...but also” can be used with adjectives and then clauses, but it’s often followed by parallel structure.

Perhaps it’s meant to be: “Jack was not only quick but also accurate in solving the puzzle.” — but “accurate” isn’t there.

Maybe the second blank is for “also”, and the phrase is “in solving the puzzle” modifying the whole thing.

I think the intended answer is not only...but also, as it’s commonly used to add emphasis.

Similarly, sentence 5: “That was ______ an inspirational speech ______ everyone listened with great attention.”
Here, “not only...but also” can be used to add a consequence, though it’s not its primary use.

For example: “It was not only raining but also flooding.” — adding another fact.

Here, “everyone listened” is a result, but perhaps in this context, it’s accepted.

Some sources say “not only...but also” can introduce a surprising additional fact.

So I’ll go with not only...but also for sentence 5.

Now sentence 2: “______ Mia ______ Max would drive the car.”
We said “Either...or”, but let’s confirm.

If it were “Both...and”, it would be “Both Mia and Max would drive the car.” — but then the verb should be “would drive” (plural), which it is — “would” is the same for singular and plural.

“Would” doesn’t change, so “Both Mia and Max would drive” is fine.

But the sentence doesn’t specify if both or one. However, in context, if it’s “the car”, probably only one drives at a time.

But without more context, “either...or” implies a choice, “both...and” implies both.

The sentence is neutral, but typically, for driving a car, it’s one person.

Moreover, in many worksheets, “either...or” is used for choices.

I think Either...or is correct.

Sentence 4: “______ Ethan ______ Evan was invited to the wedding.”
Verb is “was” — singular. If it were “both...and”, it should be “were invited”.

Since it’s “was”, it must be only one person, so Either...or.

Yes.

Now sentence 7: “The bus will leave on time ______ we reach ______ not.”
As discussed, “either...or” is the only possible choice from the list.

So I’ll go with that.

Let’s compile all answers:

1. not only...but also
2. Either...or
3. not only...but also (assuming it's adding emphasis)
4. Either...or
5. not only...but also (adding the effect)
6. both...and
7. either...or
8. both...and

But let’s verify sentence 3 again. Perhaps it’s “both...and”?

“Jack was both quick and in solving the puzzle.” — that doesn’t make sense because “in solving the puzzle” isn’t an adjective.

Whereas “not only quick but also [he was good] in solving the puzzle” — implied.

I think it’s acceptable.

Similarly, for sentence 5, “not only an inspirational speech but also [it made] everyone listen” — implied.

Okay, I think this is as good as it gets.

Final Answers:

1. not only...but also
2. Either...or
3. not only...but also
4. Either...or
5. not only...but also
6. both...and
7. either...or
8. both...and

Note: For sentence 7, "either...or" is used even though "whether...or" is more natural, but since it's not an option, we use what's available.

Also, capitalization: in the answers, we should match the case as per the sentence. In sentence 2, it starts with blank, so "Either" capitalized. Others may not need capitalization unless start of sentence.

In the worksheet, the blanks are in the middle, so probably lowercase except when starting sentence.

But in the answer, we can write the pair as is.

For the final answer, I'll list them as pairs.
