Two Choices From the Same Family

Transition questions give you four words, but often two of them belong to the same family: both signal contrast, or both signal addition, or both signal a concession. That's deliberate. It means picking the right family only gets you halfway. The second half is telling the two family members apart, and that comes down to three things: strength (does the second sentence mildly qualify the first, or flatly reverse it?), scope (does it reverse the whole claim, or just one piece of it?), and what kind of sentence follows (a balanced parallel statement, or a concession that pushes back against something just conceded).

Take 'however' versus 'on the other hand.' Both mark contrast, but 'on the other hand' wants two claims of equal weight set side by side, like two renovation strategies each solving a different problem equally well. 'However' is more flexible and can also introduce an outright reversal. If the sentence before and the sentence after read like a balanced pair, matched in structure and importance, 'on the other hand' is the tighter fit. Nevertheless versus however works differently again: 'nevertheless' specifically signals that something held up or continued despite an obstacle just mentioned, so it suits a concession-then-pushback pattern rather than a flat contrast.

This is why picking any word from the correct family usually doesn't earn the point. The test is not checking whether you know contrast from addition; it's checking whether you read the two sentences closely enough to feel their exact relationship. The extension case pushes this further: sometimes all four choices come from the same family, and only register or formality separates them, so the skill chains directly into the sentence-combining task next door, where you build one sentence from notes to hit a stated goal and tone matters just as much as logic.
