Which sentence correctly uses "as long as" to state the sufficient condition for stable throughput?
"As long as the queue depth stays below 1,000, throughput remains stable" is correct: present simple after "as long as" states an ongoing sufficient condition, matching present simple in the main clause. Option B's "will stay" incorrectly future-marks a clause that should describe a standing condition. Option C shifts to past tense, wrongly suggesting the condition is a completed, one-time event rather than an ongoing state. Option D uses a bare gerund instead of a finite verb, which breaks the clause after "as long as".

Which sentence best shows the difference between "as long as" (sufficient condition) and a plain "if" (possible condition)?
"As long as the disk has free space, backups will keep running" correctly uses "as long as" to frame free disk space as the single sufficient and necessary condition for backups continuing, a stronger and more specific claim than a plain "if". Option A is grammatically odd and circular, restating "if" and "as long as" about the same fact without a clear structure. Options C and D incorrectly stack the two connectors together, which is redundant and non-standard.
3 / 5
Which sentence correctly uses "so long as" (a formal variant of "as long as") in a service-level statement?
"So long as requests stay under the rate limit, the API returns 200 responses" is correct: "so long as" behaves identically to "as long as", taking present simple to state a standing sufficient condition. Option B incorrectly substitutes "that" for "as", which is not the fixed form of this connector. Option C adds an unneeded "will stay". Option D shifts to past tense, which does not fit a general, ongoing rule about API behavior.
4 / 5
Which sentence correctly uses "as long as" to describe a condition attached to continued support for a legacy client library?
"We will keep patching the v1 client as long as any customer still depends on it" is correct: present simple after "as long as" states the ongoing sufficient condition for continued support, while the main clause can freely use "will" since it is the actual prediction. Option B unnecessarily adds "will" inside the "as long as" clause itself. Option C incorrectly shifts to past tense in a clause describing a current, ongoing state. Option D uses a bare gerund without a finite verb, which is not grammatical after this connector.
5 / 5
Which sentence correctly negates the condition using "as long as" in a monitoring alert rule?
"As long as CPU usage doesn't exceed 80%, the autoscaler stays idle" is correct: negated present simple after "as long as" states the standing sufficient condition for the autoscaler remaining idle. Option B's present continuous incorrectly frames a general threshold rule as something happening right now. Option C's "won't exceed" incorrectly future-marks a clause meant to state a general, ongoing rule. Option D shifts to past tense, which does not match the present, ongoing nature of the monitoring rule.
