Which sentence correctly uses "as of" to mark a present-moment cutoff in a status report?
"As of this writing, 12 of the 15 shards have finished reindexing" is correct: "as of" + a time reference marks the exact point the statement is true. Option B redundantly stacks "since" after "as of". Option C incorrectly substitutes "from" for "of" in this fixed phrase. Option D combines both prepositions ungrammatically.
2 / 5
Choose the sentence that correctly uses "as of" + version number to mark a change taking effect at a specific release in a changelog.
"As of version 4.2, the legacy authentication endpoint is disabled by default" is correct: "as of" + version marks the point from which the new state applies, paired with present tense for a still-current fact. Option B incorrectly uses the past tense and the ungrammatical "disable" form, plus a redundant "formerly". Option C swaps in "as for", which introduces a topic rather than a temporal cutoff. Option D adds a redundant "at".
3 / 5
Select the sentence that correctly uses "as of" to mark a future effective date, distinct from "since" (which requires a past starting point continuing to now).
"As of next Monday, all new deployments will require a signed manifest" is correct: "as of" can mark a future cutoff, paired here with future "will require". Option B misuses "since", which requires a past time reference and a perfect tense, not a future date. Option C redundantly combines "as of" and "since". Option D pairs the future date with the present perfect "have required", a tense mismatch.
4 / 5
Which sentence correctly uses "as of" to mark a past cutoff point after which a fact became true, paired with present tense for the ongoing result?
"As of the last audit, all production secrets are stored in the vault instead of environment variables" is correct: the present tense "are stored" correctly describes the still-true state resulting from that past cutoff. Option B drops the auxiliary "are", making the sentence ungrammatical. Option C uses the bare form "store" instead of the past participle "stored". Option D scrambles the fixed phrase's word order.
5 / 5
Choose the sentence that correctly distinguishes "as of" (marking a cutoff point) from "from" (marking a starting point of a duration) in the same release note.
"As of this release, dark mode is the default; from this point on, the light theme is opt-in" is correct: both phrases are used idiomatically and consistently — "as of" marks the cutoff, "from ... on" marks the ongoing duration afterward. Option B swaps them into less natural combinations. Option C repeats "as of" where "from ... on" reads more naturally for the second clause, without necessarily being wrong, but redundantly adds "too" and loses the intended contrast. Option D incorrectly merges both prepositions in the first clause.
