70% to passIt is generally not advisable to drive a wedge into a crack occurring in the hull because wedges _______________.
Awill work loose
Bwill splinter
Ctend to open the crack
Dwill pull through the plating
AI Explanation
The correct answer is C) tend to open the crack. Driving a wedge into a crack in the hull is generally not advisable because the wedge will tend to open or widen the crack, rather than closing or repairing it. Wedges are designed to split or separate materials, not to bind them together. Inserting a wedge into a crack can cause the crack to propagate and worsen the damage to the hull. The other answer choices, such as the wedge working loose or splintering, or pulling through the plating, are also undesirable outcomes but are secondary to the primary issue of the wedge opening the crack further.
