Choose the correct comparative: "GraphQL is _____ REST for highly nested data queries."
Comparatives use "more + adjective + than": "more efficient than." "As" is used in equal comparisons ("as efficient as"). "Most" is a superlative. Use the adjective form ("efficient"), not the adverb ("efficiently"), after "more."

Choose the best superlative: "Kafka offers _____ throughput of all the message brokers we evaluated."
One-syllable adjectives form superlatives with "-est": "the highest." Multi-syllable adjectives use "most": "the most reliable." Always use "the" before a superlative. "Most highest" is a double superlative — always incorrect.

Complete the contrast: "Polling checks for updates at intervals, _____ webhooks deliver events immediately."
"Whereas" connects two contrasting clauses in a single sentence. "Although" can also work but typically inverts emphasis. "Despite" requires a noun phrase or gerund, not a clause. "However" is a sentence connector, not a subordinating conjunction.
4 / 5
Which sentence uses "unlike" correctly?
"Unlike + noun phrase, clause" is the correct structure. "Unlike REST" introduces a noun phrase for comparison, followed by the main clause. Do not add "to" after "unlike." Ensure the subjects of "unlike" and the main clause are comparable.
5 / 5
Choose the sentence with correct parallel structure:
"Both X and Y" requires parallel grammatical structure: both must be the same part of speech. "Both PostgreSQL and MongoDB" — two noun phrases — is correct. "Both ... or ..." is always wrong; use "either ... or ...".
