I believe that the correct quotation among the choices which
best describes loyalty of his crew is:
“<span>They tied me up, then, plumb / amidships, back to
the mast, lashed to the mast, / and took themselves again to rowing.”</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.
