answer is- lacks parallel parts

Ms. Sue, run-on was incorrect

Run on and dangler are both incorrect. I am not sure of the correct answer though but i was marked wrong for both answers in two attempts.

Yes.

How would you rewrite it?

It is that, too!

Ms. Sue is correct in that this is a run-on sentence. It's two sentences. The first sentence modifies the second, so, in that sense, is a misplaced modifier, but it is not a phrase within a sentence, it is a different sentence. It's also convoluted in that "It is not the easiest thing to do" is expanded, modified, elucidated by the "challenging and exhilarating." I could rewrite it as one sentence or as two.

To determine whether the given sentence is a dangler sentence, we first need to understand what a dangler sentence is.

A dangler sentence is a sentence in which the subject and the modifying phrase do not clearly refer to the same noun. This can result in confusion or ambiguity for the reader.

Now, let's examine the given sentence: "Learning is to sail challenging and exhilarating; it is also not the easiest thing to do."

In this sentence, the word "learning" is the subject, and "sail challenging and exhilarating" is the modifying phrase. On its own, the modifying phrase doesn't have a clear noun to refer to, which indicates a possible dangler.

To make the sentence clearer and reduce the potential for ambiguity, we can revise it by rephrasing or repositioning the modifying phrase. For example:

"Sailing is challenging and exhilarating; learning to sail is also not the easiest thing to do."

In this revised version, the subject "sailing" directly corresponds to the modifying phrase "challenging and exhilarating." Therefore, the sentence is no longer a dangler sentence.

Remember, it's important to ensure that the subject and modifying phrase in a sentence are properly aligned to convey the intended meaning clearly to the reader.

A dangler is a misplaced modifier. Your sentence is a runon sentence.
