Context: Viggo pressed on , hoping to reach his estate by nightfall . They stopped briefly at midday to share some of the provisions that Orlando had packed for them , but they ate in a hurry , for it seemed likely that it would soon start to rain and their open carriage would provide little cover . Although there should have been at least an hour of daylight left , it soon became very dark , the thickening clouds obscuring all remaining light . They found themselves driving through dense woods , the horses neighing and pulling at the reins , making the carriage shake .

Question: What might be different if they did n't have an open carriage ?
Options:
0. They would have cover from the rain
1. They would n't be driving through the dense woods
2. None of the above choices .
3. They would n't have cover from the rain
Answer: 0
