Question

if you are driving on a road with only one lane in each direction and you want to pass, but a curve ahead blocks your view, you must: not pass the other vehicle signal longer than five seconds to pass safely increase your speed to pass safely honk your horn to make other drivers slow down

Explanation:

When driving on a one - lane - per - direction road and there's a curve blocking the view, passing is unsafe as you can't see oncoming traffic. Signaling longer, speeding up, or honking don't address the safety risk from the blocked view. So the correct action is not to pass.

Answer:

Not pass the other vehicle
