In the analogy “Tennis is to sport as Chemistry is to ____”, which option best completes the relationship?

Introduction / Context:
This analogy question relates specific fields to their broader categories. Tennis is a particular game that falls under the larger category of sport. Chemistry is a specific field of study, and the task is to identify which option names its broader category in the same way. Such questions test your understanding of how subjects and disciplines are classified.

Given Data / Assumptions:

• First pair: Tennis and sport.
• Second pair: Chemistry and an unknown category.
• Options: biology, physics, science, subject, experiment.
• We assume standard academic classification of disciplines.

Concept / Approach:
The relation “Tennis : sport” is that tennis is a type of sport. We need a category that stands to chemistry in the same way, meaning “chemistry is a type of this broader field.” Chemistry, along with physics and biology, is one of the main branches of science. Therefore the correct category is science, because chemistry is a science, just as tennis is a sport.

Step-by-Step Solution:

Step 1: Analyse the first pair. Tennis is a specific game; sport is the general category that includes tennis. Step 2: Identify the pattern as “specific type to general category.” Step 3: Apply this to chemistry. Chemistry is a field that belongs to a larger area of human knowledge. Step 4: Among the options, biology and physics are also specific sciences and are on the same level as chemistry, not above it. Step 5: Science is the broader discipline that includes chemistry, so “chemistry : science” matches “tennis : sport.”

Verification / Alternative check:
Consider how these words are used in school or university contexts. Students may say “I enjoy science, especially chemistry” in the same way that someone says “I love sport, especially tennis.” The words biology and physics are parallel to chemistry, so they cannot be the larger class. Subject is a very general term, but tennis is not simply any subject; it is specifically a sport. Experiment is an activity carried out in science, not a category. The only option that functions as a proper superclass to chemistry is science.

Why Other Options Are Wrong:
Biology and physics are peers of chemistry, not its super category, so choosing them would break the analogy structure. Subject is too broad and vague, and there is no conventional expression “chemistry is a subject” used as a classification pair in the same focused way as “tennis is a sport.” Experiment is a method or activity within chemistry, not the field to which chemistry belongs. Science is the correct overarching grouping.

Common Pitfalls:
Some candidates are tempted by biology or physics because they associate these strongly with chemistry in the science stream. Others pick subject because any topic in school is a subject. However, the analogy is about specific to general in a recognised classification tree, and that structure is best seen by matching tennis to sport and chemistry to science. Always check whether your answer represents the correct level of generality.

Final Answer:
The correct completion is that chemistry stands to science as tennis stands to sport.
