In the following question, out of the four alternatives, choose the one which can be substituted as a single word for the description: "A place for fish or water plants."

Introduction / Context:
This one-word substitute question focuses on words for special places where certain types of living things are kept. Here, the description is "A place for fish or water plants." English vocabulary gives specific terms for enclosures used for birds, bees, plants, and aquatic life, and it is important for exam candidates to distinguish them clearly.

Given Data / Assumptions:

• Description: a place for fish or water plants.
• We are dealing with an enclosed environment used for keeping aquatic life.
• Options: Aviary, Apiary, Herbarium, Aquarium, Vivarium.
• We assume basic science and general knowledge of environmental vocabulary.

Concept / Approach:
An "aquarium" is a tank, bowl, or glass container in which fish and water plants are kept. The word comes from "aqua" meaning water. An aviary is for birds, an apiary is for bees, a herbarium is a collection of dried plants, and a vivarium is a general enclosure for live animals or plants. Only "Aquarium" directly matches the idea of a place specifically designed for keeping fish and aquatic plants.

Step-by-Step Solution:
Step 1: Identify the key detail: the place is meant for fish and water plants.Step 2: Recall common words used for enclosures: aquarium (fish), aviary (birds), apiary (bees).Step 3: Connect "aqua" with water and remember that an aquarium holds water.Step 4: Confirm that "Aquarium" appears in the option list.Step 5: Eliminate the other options as they refer to different types of collections and enclosures.

Verification / Alternative check:
Think of what people keep in their homes or in public places like malls and hotels. When you see a glass tank with colourful fish and water plants, you call it an aquarium. You never say "Look at that beautiful aviary" when pointing to fish. In contrast, an aviary is a large cage or building for keeping birds, such as parrots or pigeons. Thus usage in real life clearly supports "aquarium" for the description in the question.

Why Other Options Are Wrong:

• Aviary: A large cage or house for birds, not for fish or aquatic plants.
• Apiary: A place where beehives are kept, used by beekeepers.
• Herbarium: A collection of dried plant specimens, usually for scientific study, not a living water environment.
• Vivarium: A general enclosure for keeping live animals or plants, such as reptiles or insects, but not specifically focused on aquatic life.

Common Pitfalls:
Examinees often mix up aviary, apiary, and aquarium because they sound similar. A helpful memory trick is to associate "aqua" with water, "avi" with birds (as in aviation), and "api" with bees (think of honey). Build these little associations so that you can quickly map each enclosure word to the correct living things during the exam.

Final Answer:
The correct one-word substitute for a place for fish or water plants is Aquarium.
