Meaning: 'Deposits' means to place or put something down in a specific location, in this case, the larvae into the ocean.

Wrong options:

• receives: The verb 'receives' implies taking in something, which does not fit the context of releasing larvae into the ocean.
• eats: The verb 'eats' suggests consumption, which is not relevant here as the crab is not consuming the larvae but rather releasing them.
• values: The verb 'values' indicates appreciation or worth, which does not apply to the action of releasing larvae.

Correct answer: float

Explanation: The verb 'float' is appropriate as it describes the action of the larvae moving on the surface of the water, which is contextually accurate. It is in the present tense and matches the subject 'the babies', indicating what they do in the ocean currents.

Meaning: 'Float' means to rest or move on the surface of a liquid without sinking, which describes how the larvae behave in the ocean.

Wrong options:

• drown: The verb 'drown' implies sinking and dying in water, which contradicts the intended meaning of the larvae moving in the ocean.
• jumps: The verb 'jumps' suggests a sudden movement upwards, which does not accurately describe the passive action of larvae in water.
• swims: The verb 'swims' implies active movement through water, which is not the best fit as the context suggests a more passive action.

Correct answer: bulk

Explanation: The verb 'bulk' fits grammatically as it indicates the action of growing larger or gaining mass, which is relevant to the context of young coconut crabs as they grow. It is in the present tense and matches the subject 'young coconut crabs'.

Meaning: 'Bulk' means to grow in size or mass, which describes the process of young crabs increasing in size as they adapt to land living.

Wrong options:

• move: The verb 'move' is too general and does not specifically convey the idea of growing larger, which is the focus of this sentence.
• make: The verb 'make' implies creating or forming something, which does not fit the context of growth in size.
• fills: The verb 'fills' suggests occupying space, which does not accurately describe the growth process of the crabs.

Correct answer: armor

Explanation: The noun 'armor' is suitable as it refers to a protective covering, which is contextually relevant since juvenile crabs use shells for protection. It fits grammatically as a noun that complements the action of using a coconut husk or sea shell.

Meaning: 'Armor' refers to a protective covering that shields an organism, in this case, the crab using shells for safety.

Wrong options:

• friend: The noun 'friend' does not fit contextually as it implies companionship rather than protection, which is the focus here.
• shadow: The noun 'shadow' suggests a dark shape or outline, which does not relate to the protective function of shells.
• representing: The word 'representing' is a verb form that does not fit grammatically as a noun in this context.

Correct answer: accomodate

Explanation: The verb 'accomodate' fits grammatically as it indicates the ability to provide space for something, which is relevant to the context of shells being large enough for the crabs. It is in the present tense and matches the plural subject 'shells'.

Meaning: 'Accomodate' means to provide enough space or room for something, in this case, the shells needing to be large enough for the crabs' size.

Wrong options:

• keep: The verb 'keep' implies holding onto something, which does not fit the context of providing space for the crabs.
• pounce: The verb 'pounce' suggests a sudden attack or leap, which is irrelevant to the context of finding suitable shells.
• segregate: The verb 'segregate' means to separate or divide, which does not apply to the context of needing space for growth.
