An architect is describing a trade-off. Which sentence uses "however" correctly?
Option B is correct. "However" is a conjunctive adverb — it connects two independent clauses but cannot join them with only a comma (that would be a comma splice, as in Option A). It must follow a full stop or a semicolon: "statement. However, continuation." or "statement; however, continuation." Option C has no punctuation at all — ungrammatical. Option D places "however" at the start of the first clause — but "however" for contrast connects to the previous statement, not to the clause it begins. Use "however" after the full stop: the first clause states the advantage, and "however" signals the counter-point.

Which sentence correctly uses "although" to describe a technical trade-off?
Option B is correct. "Although" introduces a subordinate concessive clause: Although [concession], [main point]. The subordinate clause ("Although the latency is higher") is followed by a comma and the main clause ("the system is significantly more resilient"). Option A adds "but" — this is redundant and ungrammatical; "although" and "but" both signal contrast, so using both creates a double connector error. Option C inserts "although but" — same error. Option D misplaces the comma. Pattern: "Although [drawback], [benefit]." or "[Benefit], although [drawback]."

A post-mortem uses "despite" to explain an unexpected failure. Which version is grammatically correct?
Option C is correct. "Despite" is a preposition, so it is followed by a noun or noun phrase (a gerund phrase here: "the circuit breaker being enabled"). Option A uses "despite" + subject + verb — incorrect: "despite" cannot directly precede a full clause. Option B adds "of" — "despite of" does not exist in standard English (this is a confusion with "in spite of"). Option D uses "despite that" + clause — also non-standard. The correct patterns are: Despite + noun/gerund phrase, or In spite of + noun/gerund phrase, or Even though / Although + subject + verb.

Which sentence uses "whereas" correctly to compare two technical approaches?
Option B is correct. "Whereas" is a subordinating conjunction that introduces a contrast clause. It is placed between the two contrasted clauses without a comma before it (or, less commonly, at the start of the sentence followed by a comma at the clause boundary). Option A repeats "whereas" twice — only one is needed. Option C places a comma after "whereas" — incorrect. Option D uses "whereas" to start a sentence fragment — "whereas" introduces a subordinate clause, which cannot stand alone. The pattern: [Clause A], whereas [Clause B] — no comma before "whereas" in mid-sentence.

A system design document describes a trade-off. Which sentence uses "even though" correctly?
Option A is correct. "Even though" is a stronger form of "although" — it emphasises that the concession is surprising or contrary to expectation: "Even though [surprising concession], [main point that contradicts it]." The concession is that the monolith is easier to deploy; the main point is that the team chose microservices anyway (for scalability). Option B adds "but" — double connector error. Option C places a comma after "even though" before the clause — incorrect. Option D reverses the logic: placing the team's decision in the concession position and the simpler monolith fact as the main point reverses the intended meaning.
