Which sentence correctly forms an exclamative with "what" to react to a messy codebase during a review?
"What a mess this codebase is!" is correct: the "what"-exclamative with a countable singular noun requires the indefinite article "a", followed by subject + verb in normal (non-inverted) order. Option B omits the required article "a" before the countable noun "mess". Option C incorrectly inverts subject and verb ("is this codebase"), which is not used in exclamative "what" sentences (unlike questions). Option D incorrectly uses "how" with a noun phrase; "how" exclamatives take adjectives or adverbs, not noun phrases like "a mess".
2 / 5
Which sentence correctly forms an exclamative with "how" to react to the speed of a new caching layer?
"How fast the new caching layer is!" is correct: "how" + adjective is followed by subject + verb in normal order for an exclamative (not a question). Option A incorrectly inverts subject and verb, turning the exclamative into a question form. Option B incorrectly uses "what" with a bare adjective; "what" exclamatives require a noun phrase, not just an adjective. Option D places "fast" after the verb instead of directly after "how", which breaks the required exclamative pattern.
3 / 5
Which sentence correctly forms a "what" exclamative with a plural, uncountable-style reaction to a set of test results?
"What impressive results the load test produced!" is correct: with a plural noun ("results"), the "what"-exclamative omits the article entirely, going straight from "what" + adjective + plural noun into subject + verb order. Option B incorrectly adds the article "a" before a plural noun, which is ungrammatical. Option C incorrectly inverts to question order ("did the load test produce"), which is not used in exclamatives. Option D incorrectly uses "how" before a noun phrase, which "how"-exclamatives do not take.
4 / 5
Which sentence correctly forms an exclamative with "how" and an adverb to react to how quickly a bug was fixed?
"How quickly the team fixed that bug!" is correct: "how" + adverb ("quickly", describing the manner of the verb "fixed") is followed by normal subject-verb order. Option A incorrectly uses question-style subject-auxiliary inversion ("did the team fix"). Option B incorrectly uses "what" before an adverb, which is not grammatical; "what" exclamatives need a noun phrase. Option C incorrectly uses the adjective form "quick" instead of the adverb "quickly" to modify the verb "fixed".
5 / 5
Which sentence correctly forms a "what a/an" exclamative with a singular countable noun to react to a well-designed API endpoint?
"What an elegant solution this endpoint is!" is correct: since "solution" is a singular countable noun starting with a vowel sound, the indefinite article "an" is required after "what", followed by normal subject-verb order. Option B omits the required article "an" before the vowel-initial noun "elegant". Option C incorrectly uses "how" before a full noun phrase, which is ungrammatical. Option D incorrectly inverts subject and verb at the end ("is this endpoint"), which is not used in exclamative sentences.
