Here's why:
* Dangling Modifier: A dangling modifier is a phrase or clause that modifies a word or phrase that is not clearly stated in the sentence. In this case, "Having risen because of rains" is modifying the hiker, but the hiker is not the one who rose.
Let's break down the sentence:
* "Having risen because of rains..." This phrase implies that something rose.
* "...hiker were unable to cross the river." This tells us the hiker was unable to cross the river.
The problem is that the phrase "having risen because of rains" doesn't logically connect to the hiker. It sounds like the hiker is the one who rose, which makes no sense.
How to Fix it:
To correct the sentence, we need to make it clear who or what is being modified by the phrase "having risen because of rains." Here are some options:
* "Because of the heavy rains, the river had risen, and the hiker was unable to cross it." This clarifies that the river rose, not the hiker.
* "After the rains caused the river to rise, the hiker was unable to cross it." This provides more context and explicitly connects the rising river to the hiker's inability to cross.
