5 exercises — forming regular, irregular, and emphatic superlatives correctly in comparisons and technical reports.
Key patterns:
-est — short adjectives (slowest, fastest, largest)
the most + adjective — longer/multi-syllable adjectives (the most efficient)
good→best, bad→worst — irregular superlatives, never "goodest" or "more best"
one of the + superlative + plural noun — noun after superlative must be plural

A performance report states: "Of the three caching strategies tested, write-through was _____." Which superlative form is correct?
For short, one-syllable adjectives like slow, the superlative is formed with the suffix -est, giving the slowest. "The most slow" incorrectly applies the periphrastic superlative pattern reserved for longer adjectives. Slower and more slow are comparative forms, appropriate only when comparing exactly two items — but this sentence compares three strategies, which requires the superlative.

An architecture review notes: "This is _____ efficient design we have proposed so far, given the constraints." Which superlative form is correct for a longer adjective?
Multi-syllable adjectives like efficient form their superlative periphrastically with "the most" rather than an -est suffix, which sounds unnatural or ungrammatical ("efficientest" is not a word). The definite article the is required before a superlative functioning as a complement identifying one specific item from a set, so "most efficient" alone (option D) is missing the article.

Which sentence correctly uses a superlative to describe a service among several alternatives in a vendor comparison?
"Good" is an irregular adjective whose superlative form is best, not a regularly formed -est or most construction. "Goodest" and "most good" are both ungrammatical, and "more best" is a double-superlative error, stacking a comparative marker onto an already-superlative irregular form. Irregular adjectives like good→best, bad→worst, and far→furthest/farthest must be memorized individually.

A capacity-planning document states: "This is _____ significant bottleneck identified in the load test." Which superlative structure correctly signals that this bottleneck stands out even among other serious ones (an emphatic superlative)?
Adding an intensifier such as "by far" after a superlative — "the most significant by far" — is a common way to emphasize that an item is not just marginally but overwhelmingly the extreme case in its category. "More significant" is comparative, not superlative, and would require an explicit comparison ("more significant than X"). "Quite significant" uses a degree modifier but makes no superlative claim at all, understating the intended emphasis.
5 / 5
Which sentence correctly uses "one of the" with a superlative in a technical write-up, following standard subject-verb agreement rules?
The construction "one of the + superlative + plural noun" requires the noun following the superlative to be plural ("causes"), since it refers to one member of a larger set of common causes, while the main verb agrees with the singular subject "this" ("is"). Option B incorrectly uses a singular noun ("cause") after the plural-triggering "one of the," and option C incorrectly makes the main verb plural ("are") when it should agree with the singular demonstrative subject "this."
