can someone explain why C is incorrect?
laws "that require" -- is it a modifier issue?

if law is used to desribe the text itself, ing modifier is used. Whereas if it used to express the intention of law, infinite is used.

Quite simply subject verb agreement error.

C - their compliance with laws that require turtle-excluder devices on shrimp nets protect adult sea turtles.

or, their compliance... protect adult sea turtles.

thanks a lot..... i have a problem sometimes recognizing subject / verb , but not very often as my verbal score is pretty good. (39-41). but i do notice on sentences like these, sometimes i just dont "see it". any pointers on how to prevent this mistake? What should I be "looking for" to identify S/V agreement sentence correction? Because once you see it in this problem, the answer becomes VERY easy!

The simple trick I use, if I have a doubt, is - remove all the modifiers especially the prepositional phrases. What remains is the subject that does the action and the verb, the action itself. You must have noticed that I yellowed a certain portion of the sentence. This makes the relationship much clearer.

Simplifying the sentences and removing the extra layers is the key for subject verb agreement.
