Question context
R&WThe sentence needs a transition that shows contrast between a general finding and the condition where the effect is strongest.
Guardrails
Start with a hint before revealing the choice.
Connect the explanation to the tested skill.
Queue a similar drill if the concept is shaky.

1. The first clause gives the broad result: tree cover lowers temperatures.
2. The next clause narrows that result by naming a stronger condition.
