Select all sentences that use the future form correctly for the premise given.
The phone is ringing; I will answer it.✓Respuesta correcta
That crate looks far too heavy — I help you with it.
That fence is leaning farther with every gust; it is going to fall.✓Respuesta correcta
Look at those thick black clouds — it rains in a few minutes.
Explicación
Answering the ringing phone is an immediate decision, so will is appropriate, while the visibly leaning fence provides present evidence for a going-to prediction. The offer with I help wrongly uses the present simple for a spontaneous response, and the clouds sentence wrongly uses the present simple for an evidence-based prediction.
