According to the passage about ants, choose the option that correctly describes the kind of homes army ants make.

Introduction / Context:
This question tests your understanding of a particular detail in the passage about different types of ants and their homes. The passage contrasts ants that build mounds or live in wood with army ants that behave quite differently. Army ants are described as not building permanent homes at all; instead, they move in large groups in search of food. Correctly identifying this special behaviour is the key to answering the question.

Given Data / Assumptions:

The passage states that many ants build simple mounds out of dirt or sand.

Other ants use small sticks mixed with dirt and sand to make stronger mounds.

Western Harvester ants build a small mound and then dig deep tunnels for winter hibernation.

Some ants live in wood like termites.

The passage specifically notes that army ants do not make a home at all but travel in large groups searching for food.

Concept / Approach:

To solve this question, you must carefully distinguish between the behaviours of different ant types described in the passage. The phrase do not make a home at all clearly refers only to army ants, not to the others. Any option that attributes mound building, wood dwelling, or other kinds of home construction to army ants is therefore incorrect. Only the option that describes constant movement in large groups while searching for food matches the information given.

Step-by-Step Solution:
Step 1: Recall the exact line about army ants: Army ants do not make a home at all but travel in large groups searching for food. Step 2: Examine option a: They make simple little mounds out of dirt or sand. This behaviour refers to many other ants, not army ants. Step 3: Examine option b: They make stronger mounds of sticks mixed with dirt and sand. This describes another type of ant that reinforces its mound for protection from rain. Step 4: Examine option c: They make small mounds on top with tunnels up to fifteen feet below. This behaviour belongs to Western Harvester ants. Step 5: Examine option d: They do not make homes but travel in large groups searching for food. This exactly matches the passage description of army ants. Step 6: Examine option e: They build nests inside wood like termites. This is stated about some ants in general, not specifically about army ants. Step 7: Conclude that option d is the correct answer.

Verification / Alternative check:

If you reread the paragraph about ant homes, you will see that each type of dwelling or behaviour is linked to a particular phrase: simple mounds, stronger mounds, deep tunnels, living in wood, and travelling in groups. Only the description of army ants contains the strong phrase do not make a home at all. This makes it easy to match with the correct option once you pay attention to that unique feature.

Why Other Options Are Wrong:

Option a describes a general category of ants that build simple mounds, not army ants.

Option b applies to those that use sticks mixed with dirt and sand for stronger mounds.

Option c is specific to Western Harvester ants and their deep tunnels.

Option e refers to ants that live in wood like termites, which are again different from army ants.

Common Pitfalls:

Candidates may confuse the behaviours because all descriptions occur in a single paragraph. They might select an option mentioning mounds or wood simply because they remember these words from the passage. To avoid such errors, it is useful to mentally group each description with its specific subject and to notice words like some ants, other ants, and army ants that signal a change of focus.

Final Answer:

According to the passage, army ants do not make homes but travel in large groups searching for food.
