It was August and our clothes were stifling, but we ( would need / will need ) the warmth from our bodies sealed around us as we hiked into the high altitudes.
I don’t see how “will need” is an incorrect answer.
“As we hiked” doesn’t make sense when paired with future tense.
“We will need them as we hike,” sure – that’s future and present subjunctive, I think. But future and past doesn’t work.
The tense of the sentence is past(were stifling–> were indicates past) so you can choose the option that indicates past tense(would)
Oh right. Thanks.
