Question

Please proofread:

Gravity pulls both the skydivers downwards the same way. Air pushes them up, and the force of the push increases with their speed. This is called air resistance. The heavier skydiver has more speed as they fall and reach a higher terminal velocity than the skydiver who is lighter. If any of the skydivers deploy their parachute, their air resistance is increased and they fall much slower.


Keep my wording and list all errors. you do not need to change all the sentences, just ones that really need it. if you see a sentence is fine / good as is, dont bother to change it.

Answer 1

Thanks — I’ll list the errors and give corrected versions only where needed.

Original text (numbered):
1. Gravity pulls both the skydivers downwards the same way.
2. Air pushes them up, and the force of the push increases with their speed.
3. This is called air resistance.
4. The heavier skydiver has more speed as they fall and reach a higher terminal velocity than the skydiver who is lighter.
5. If any of the skydivers deploy their parachute, their air resistance is increased and they fall much slower.

Errors and suggested fixes:

1) Sentence 1
- Errors: extra article and wording/word order.
- "both the skydivers" → should be "both skydivers".
- "downwards the same way" is awkward; more idiomatic is "downward in the same way" (or "downwards in the same way" in British English).
- Suggested correction: Gravity pulls both skydivers downward in the same way.

2) Sentence 2
- No change needed. (Stylistic alternatives exist, but the sentence is acceptable as written.)

3) Sentence 3
- No change needed.

4) Sentence 4
- Errors:
- Subject-verb agreement: "The heavier skydiver has ... and reach" — "reach" should be "reaches".
- Awkward phrasing: "has more speed as they fall" is clumsy; use "gains more speed" or "falls faster."
- Suggested correction: The heavier skydiver gains more speed as they fall and reaches a higher terminal velocity than the lighter skydiver.

5) Sentence 5
- Errors:
- Verb agreement/number: "If any of the skydivers deploy" is marginal — better phrasing is "If any skydiver deploys" or "If any of the skydivers deploys".
- Incorrect comparative form: "fall much slower" — when modifying a verb, use an adverb: "fall much more slowly."
- Suggested correction: If any skydiver deploys their parachute, their air resistance increases and they fall much more slowly.

Notes:
- Using singular "they/their" is acceptable here to avoid gendered pronouns.
- I changed only the sentences that needed grammatical or clarity fixes; sentences 2 and 3 were left as-is.
