Let’s go through each word and pick the best prefix from the bank that makes a real, common English word.

We’ll go row by row, left to right.

---

Row 1:

- ___ fix → prefix (a thing added before)
- ___ sense → nonsense (doesn’t make sense) or missense? Wait — “nonsense” is common. Also “insense”? No. “Unsense”? Not really. So nonsense.
Wait — actually, “mis” + “sense” = missense? That’s not common. But “nonsense” is perfect. Also “in” + “sense” = insensible? Not quite. Let’s stick with nonsense for now.
Actually — hold on! There’s also “un” + “sense” = unsense? Not standard. But “pre” + “sense” = presense? No. Hmm. Maybe “mis” isn’t right. Actually, let me think again — what about “in” + “sense”? In-sense? No. Wait — maybe it’s “non”sense. Yes.

But wait — there’s another possibility: “dis” + “sense” = dissense? Not common. I think nonsense is best.

Actually — correction! The most common word here is nonsense. But let’s check others later if needed.

Wait — no! What about “mis” + “sense”? Missense? That’s a biology term. For general use, nonsense is better.

BUT — looking at the list again — maybe “in” + “sense” = insensible? No, that’s different. Let’s move on and come back.

Actually — I just realized: “un” + “happy” is obvious. Let’s do that first.

___ happy → unhappy

Okay, so:

Row 1:
- pre fix
- non sense? Or mis? Wait — let’s look up common words.

Actually — let’s be systematic.

Prefix bank: de-, ex-, im-, mis-, pre-, un-, dis-, il-, in-, non-, re-, with-

Now:

___ fix → prefix ✔
___ sense → nonsense ✔ (also “mis”sense is rare; “in”sense doesn’t work)
___ happy → unhappy ✔

Row 2:

___ mind → remind? Or unmind? “Remind” is common. “Unmind” is archaic. So remind ✔
___ pert → impert? No. “Ex”pert? Yes! Expert ✔
___ respect → disrespect ✔ (or “ir”respect? But “ir” not in bank. “Dis” is there.)

Row 3:

___ equal → inequal? Or unequal? Both exist. “Unequal” is more common. But “inequal” is not standard — it’s “unequal”. Wait — “in” + “equal” = inequal? Not really. It’s “unequal”. But “in” can be used like “incomplete”, but for “equal”, it’s “unequal”. However, “in” is in the bank. Let’s see — actually, “unequal” uses “un-”, which is in the bank. So unequal ✔
___ legal → illegal ✔ (because “l” follows, so “il-”)
___ fiction → nonfiction ✔

Row 4:

___ prove → disprove ✔ (to prove false)
___ frost → defrost ✔ (remove frost)
___ ceed → exceed ✔ (go beyond) — also “pro”ceed? But “pro” not in bank. “Re”ceed? Recede? Yes! “Recede” means go back. But “exceed” is also valid. Which one? Both are possible. But let’s see — “exceed” is more common? Or “recede”? Actually, both are good. But since the instruction says “there may be more than one answer”, we can choose one. Let’s pick exceed for now. Wait — “proceed” would need “pro-”, not in bank. “Succeed” needs “suc-”. So only “exceed” and “recede” are possible. “Exceed” is more positive/common? Let’s go with exceed. But actually, “recede” is also fine. Hmm. Maybe I should note both possibilities, but for final answer, pick one. Let’s say exceed.

Wait — let’s double-check: prefixes available: de-, ex-, im-, mis-, pre-, un-, dis-, il-, in-, non-, re-, with-

So for “ceed”:
- ex + ceed = exceed ✔
- re + ceed = recede ✔
Both are valid. Since the problem allows multiple answers, either is acceptable. I’ll put exceed for now.

Row 5:

___ lucky → unlucky ✔
___ lead → mislead ✔ (to lead wrongly)
___ fat → overfat? Not in bank. “De”fat? Defat? Like remove fat — yes, in cooking/science. “With”fat? No. “Non”fat? Yes! Nonfat milk, etc. So nonfat ✔

Row 6:

___ fair → unfair ✔
___ gust → disgust ✔
___ hold → withhold ✔ (to keep back)

Row 7:

___ place → replace ✔
___ usual → unusual ✔
___ portant → important ✔ (because “p” follows, so “im-”)

Row 8:

___ draw → withdraw ✔
___ logical → illogical ✔ (because “l” follows)
___ trieve → retrieve ✔

Row 9:

___ visible → invisible ✔
___ play → replay ✔ (or “mis”play? Misplay is a word — to play incorrectly. But “replay” is more common. Both possible. Let’s go with replay)
___ cellent → excellent ✔

Row 10:

___ view → preview ✔ (or “re”view? Review is also common. Both valid. “Preview” = see before, “review” = see again. Either works. Let’s pick preview for variety)
___ code → decode ✔ (or “en”code? “En” not in bank. “Re”code? Recode is possible. But “decode” is very common. So decode)
___ flex → reflex ✔ (as in reflex action) — also “in”flex? Inflexible? But that’s “inflexible”, not “inflex”. “Reflex” is a noun. So reflex ✔

Now let’s compile all answers, making sure they’re real words and using prefixes from the bank.

Final choices:

Row 1:
pre fix
non sense
un happy

Row 2:
re mind
ex pert
dis respect

Row 3:
un equal
il legal
non fiction

Row 4:
dis prove
de frost
ex ceed *(or re ceed — both ok, I'll use ex ceed)*

Row 5:
un lucky
mis lead
non fat

Row 6:
un fair
dis gust
with hold

Row 7:
re place
un usual
im portant

Row 8:
with draw
il logical
re trieve

Row 9:
in visible
re play *(or mis play — I'll use re play)*
ex cellent

Row 10:
pre view *(or re view — I'll use pre view)*
de code
re flex

Wait — let me verify a few tricky ones:

- “___ sense”: Is “nonsense” the only option? What about “mis” + “sense”? Missense is a technical term. “In” + “sense” = insensible? Not matching. “Un” + “sense” = unsense? Not standard. So “non”sense is best.

- “___ ceed”: “Exceed” and “recede” both valid. I chose “exceed”.

- “___ play”: “Replay” and “misplay” both valid. I chose “replay”.

- “___ view”: “Preview” and “review” both valid. I chose “preview”.

All these are correct and use prefixes from the bank.

Now, let’s write them in order as per the grid.

The grid has 10 rows, 3 columns.

So final answer list:

Column 1:
pre fix
re mind
un equal
dis prove
un lucky
un fair
re place
with draw
in visible
pre view

Column 2:
non sense
ex pert
il legal
de frost
mis lead
dis gust
un usual
il logical
re play
de code

Column 3:
un happy
dis respect
non fiction
ex ceed
non fat
with hold
im portant
re trieve
ex cellent
re flex

I think that’s all correct.

Let me quickly cross-check any doubtful ones:

- “de frost” → defrost ✔
- “mis lead” → mislead ✔
- “with hold” → withhold ✔
- “il logical” → illogical ✔
- “re trieve” → retrieve ✔
- “ex cellent” → excellent ✔
- “re flex” → reflex ✔

All good.

Some alternatives exist, but these are all valid and common.
