For J1, just match the two sides based on the keywords' topics. I did 2, 3, 5, 7, and 8 first:
2. Mentioned "stock", so categorized as "financial". A
3. Mentioned "stitch", so categorized as "medical". C
5. Mentioned "Will". B
7. Mentioned "play", so categorized as "music streaming". G
8. Mentioned "parties" and "speaker", so categorized as "political". D
Now we have 1, 4, 6 left, and D, E unused. 1 mentions "date", so it's categorized as "relationship". F. 4 mentions "free trial" and "expire" which seems sufficiently like legal domain, so E (because the other one is even less like legal). However I'm not sure about 6. It mentioned "cold" and "summer", so perhaps "medical" again. C
J2 is also straightforward.
(ab) "bee made of honey" = N1 MAKE N2. Correct: "bee that makes honey" = N2 MAKE N1
(cd) "video that is music" (can't be "have" because the response says "audio-only") = N2 BE N1. Correct: "video that has music" = N2 HAVE N1
(ef) "engine that is part of steam" = "steam has engine" = N1 HAVE N2 (can't be "be" because the response says "part of" not "is"). Correct: "engine that uses steam" = N2 USE N1. Might also be "engine that produces steam" = N2 MAKE N1.
(gh) "oil that makes olives" = N2 MAKE N1. Correct: "oil made of olives" = N1 MAKE N2
Solutions:
J1:
(Other possibilities may work as well)
J2:
a. N1 MAKE N2
b. N2 MAKE N1
c. N2 BE N1
d. N2 HAVE N1
e. N1 HAVE N2
f. N2 MAKE N1; N2 USE N1
g. N2 MAKE N1
h. N1 MAKE N2
