Suppose A group of friends decided to go on a hiking trip in the mountains for the weekend. They packed their bags, prepared their camping gear, and set out early in the morning. As they reached the halfway point of their trek, they faced unexpected heavy rainfall that forced them to take shelter in a nearby cave. They spent the night in the cave, waiting for the rain to stop before continuing their journey the next day.
Can we infer that "The friends were well-prepared for the heavy rainfall during the hiking trip"? Yes, no, or maybe?
