First of all, you need to know what a dangling modifier is. It means that there is a modifier which refers to the wrong thing in a sentence. Here, that would be 'digging to the bottom of my suitcase.' As you can see, the way this sentence is written, it would seem that modifier refers to 'my passport' as if it was digging, which is not true.
Therefore, the correct answer which fixes this problem is A. <span>Digging to the bottom of my suitcase, I failed to locate my passport, which was hidden under a pile of dirty clothes </span>
It could be
obsession. As obsession is defined as the reoccurring mental thought or idea of
something. This obsession has caught you up or to overthink. For instance in a
situation that has caught you up, you engross yourself with it. Overthinking like
obsession is a mental act or a cognitive resonance which is still different
from behavior or compulsion, as the word for it.
