Question

look at this sentence:

the water that had entered the ships hull had to be pumped out so that the ship would remain buoyant.

select the definition of buoyant that the sentence uses.

buoyant \boɪ-uhnt\\ adjective more buoyant, most buoyant 1. able to float: a ping-pong ball is buoyant in water. 2. able to keep a body afloat or cause it to rise: salt water is more buoyant than freshwater. 3. cheerful: tanners soccer team was positively buoyant after their victory. 4. successful and likely to remain successful: the market remained buoyant as trade increased. — from spanish (boyante)

Explanation:

To determine the correct definition, analyze the context: the sentence is about pumping water out of a ship's hull so the ship can stay buoyant. A ship staying afloat (able to float) matches the first definition ("able to float"). The other definitions (keeping a body afloat, cheerful, successful) don't fit the ship - related context here.

Answer:

1. able to float: A Ping - Pong ball is buoyant in water.
