In the following question, few sentences are given with two blanks in each. Select the pair of words that best completes both blanks in all the sentences, ensuring the sentences remain grammatically correct and contextually appropriate.


(I) Analysts warn that deepfake campaigns ________ public trust, yet some regulators _________ existing laws will be enough to deter abuse.
(II) If AI hiring models ___________ to encode bias, we must not ________ that transparency dashboards alone will solve the problem.
(III) While rogue chatbots seldom _____________ critical systems directly, engineers should never ________ safety until red-team tests are complete.

Correct option is C

Option c is the correct answer.
Fill with (c): threaten, presume
· (I) Analysts warn that deepfake campaigns threaten public trust, yet some regulators presume existing laws will be enough to deter abuse.
· (II) If AI hiring models threaten to encode bias, we must not presume that transparency dashboards alone will solve the problem.
· (III) While rogue chatbots seldom threaten critical systems directly, engineers should never presume safety until red-team tests are complete.
Why it works:
· threaten + direct object ( threaten public trust; threaten critical systems) and threaten to + V ( threaten to encode) are standard, idiomatic uses.
· presume naturally takes a that-clause ( presume that …) or a noun ( presume safety), both used correctly here.
· Semantics align across all three contexts (risk + assumption).
Other Options:
· (a) extinct, roll — Incorrect
· extinct is an adjective, not a verb for these slots; roll existing laws is nonsensical.
· (b) secure, fraction — Incorrect
· secure public trust could work in isolation, but fraction doesn’t collocate with a that-clause or safety here.
· (d) creates, perform — Incorrect
· Agreement: subject models (plural) ≠ creates (singular). Also perform safety is unidiomatic.
· (e) salvage, function — Incorrect
· salvage public trust might fit (I) after damage, but (II) salvage to encode bias and function safety are ungrammatical/unidiomatic.
Therefore, only (c) — threaten, presume — correctly and naturally completes all three sentences.
