Which sentence correctly uses verb phrase ellipsis to avoid repeating the main verb when contrasting two environments?
"...but the production server doesn't" is correct: the auxiliary "doesn't" alone stands in for the omitted repeated verb phrase "handle the load fine", which is standard verb phrase ellipsis triggered by contrast ("but"). Option A incorrectly retains the bare verb "handle" after "doesn't", which creates redundancy that ellipsis is meant to avoid — the auxiliary alone is sufficient. Option C spells out the full repeated phrase, which is grammatical but defeats the purpose of ellipsis and is needlessly repetitive. Option D omits the auxiliary "does" entirely, leaving an ungrammatical fragment ("the production server not") without a finite verb.
2 / 15
Which sentence correctly uses modal verb phrase ellipsis to compare what two services are capable of?
"The old one can't" is correct: the modal "can't" alone stands in for the elided repeated verb phrase "process messages in parallel", which is the standard, most natural way to avoid repetition after a modal. Option B redundantly retains the bare verb "process" after "can't", which is unnecessary since the modal alone completes the ellipsis. Option C has incorrect word order, placing "not" before "can" rather than using the contracted negative form "can't" after the subject. Option D incorrectly combines "doesn't" with "can", stacking two auxiliaries where only one modal auxiliary is needed and permitted.
3 / 15
Which sentence correctly uses "has"/"hasn't" ellipsis to compare whether two teams have completed a migration?
"...but the frontend team hasn't yet" is correct: the auxiliary "hasn't" alone elides the repeated verb phrase "finished the migration", with "yet" naturally attaching after the auxiliary to indicate the action is still pending — this is the concise, idiomatic form. Option A spells out the full repeated phrase "finished it", which is grammatical but unnecessarily repetitive given that ellipsis is available and more natural here. Option C omits the auxiliary "hasn't" entirely, leaving an ungrammatical fragment without a finite verb. Option D incorrectly switches auxiliaries from "has" to "did", which does not match the present perfect aspect established by "has finished" in the first clause.
4 / 15
Which sentence correctly uses "will"/"won't" ellipsis in a comparison of planned rollout behavior?
"Region B won't" is correct: the modal "won't" alone elides the repeated verb phrase "receive the update this week", which is the standard, concise way to express a contrasting future plan. Option A retains the bare verb "receive" without its object after "will not", creating an incomplete and redundant fragment rather than clean ellipsis. Option C has incorrect word order ("not will" instead of "will not"/"won't"). Option D incorrectly stacks "doesn't" with "will", combining two auxiliaries where only the single modal "won't" is grammatical.

A code review comment compares two functions' behavior. Choose the sentence with correctly formed verb phrase ellipsis using "did"/"didn't".
"The new one didn't" is correct: the auxiliary "didn't" alone elides the repeated verb phrase "validate input correctly", matching the past tense established by "validated" in the first clause and avoiding redundant repetition. Option A retains the bare verb "validate" after "didn't", which is unnecessary given that the auxiliary alone completes the ellipsis. Option C has incorrect word order, placing "not" before "did" instead of forming the standard contraction "didn't" after the subject. Option D incorrectly combines "hasn't" with "did", mixing present perfect and simple past auxiliaries, which is both redundant and grammatically inconsistent with the past-tense first clause.

David: 'The new API endpoint returns a 404 if the user hasn't authenticated. The old one always returned 200.'
Which of the following best completes Sarah's response, correctly using verb phrase ellipsis?
This question tests the use of 'hasn't' ellipsis to maintain consistency when contrasting past behavior. The key is recognizing that 'hasn't' is the correct auxiliary verb form to use in this comparison, reflecting the ongoing state of authentication. Option A uses the incorrect 'didn't', which doesn't align with the continuous aspect implied by the original statement.

Maria (in a Slack channel) wrote: 'The container deployment failed because it won't scale to handle the load. The previous version did.'
Which of these options best completes Maria's message, demonstrating modal verb phrase ellipsis?
This question assesses the correct use of 'won't' ellipsis for comparison. The structure 'will not' is a common modal verb phrase, and using 'won't' creates a concise and natural-sounding contrast with the previous version's behavior. Option A introduces an unrelated statement about monitoring, while options C & D incorrectly use 'we monitored'.

Ben (in a PR description) writes: 'The migration process has completed successfully. The previous one hasn't.'
Which of the following is the most appropriate revision to ensure grammatically correct verb phrase ellipsis?
This question focuses on the correct tense usage with 'has'/'hasn't' ellipsis. Using 'was completed' correctly places the action in the past perfect continuous tense, which is appropriate when describing a completed process that occurred before another event (the previous migration). Options 1 and 2 are incorrect due to using the simple past ('didn't') instead of the present perfect ('hasn't').
9 / 15
Liam (during a standup meeting) states: 'The new feature will work as expected. The previous one won't.'
Which of the following best illustrates Liam's use of verb phrase ellipsis?
This scenario tests the correct usage of 'will' ellipsis in a comparative context. Liam is contrasting the expected behavior of the new feature with the previously problematic one. Option A completes the sentence naturally while maintaining the contrast through the correct use of 'won't'. Options B & D add irrelevant information.

Chloe: 'The database query returns null if the user doesn't have permission. The old one returned an error.'
Which of these options correctly uses verb phrase ellipsis for a concise comparison?
This question assesses the appropriate use of 'hasn't' in a comparative statement. Using 'hasn't' correctly reflects the ongoing lack of permission and maintains consistency with the original phrasing. Option A is conversational but doesn't utilize ellipsis effectively; options C & D are grammatically incorrect.
