Select the related word: Contamination is to Food as Infection is to which of the following?

Introduction / Context:
This analogy focuses on how harmful processes affect particular targets. Contamination usually affects food or water, making it unsafe. You must now determine what infection primarily affects. Understanding such cause and target pairs is important both for general science and for verbal reasoning questions.

Given Data / Assumptions:
1) Contamination refers to the presence of unwanted, harmful substances in food, water, or another medium.
2) Food is a common target that becomes unsafe when contaminated.
3) Infection is the invasion and multiplication of germs or microbes in a living organism.
4) The options are Diseases, Body, Germs, and Microbes.
5) The correct answer must be the main object or target that experiences infection, similar to how food experiences contamination.

Concept / Approach:
The relationship in the model pair is Process or Harmful Condition to Object Affected. Contamination affects food, not the contaminating agents themselves. Similarly, infection affects the body of a living being, not the germs that cause it. So we look for the word that best represents the host or target of infection, which is the body. Diseases, germs, and microbes are closely related concepts, but they are not the primary object that is infected in the same way food is contaminated.

Step-by-Step Solution:
Step 1: Restate the original pair. Food can suffer contamination, meaning foreign harmful substances enter the food. Step 2: Consider what infection acts upon. Infection occurs when germs invade a living body or part of a body. Step 3: Examine option a, Diseases. Diseases are conditions resulting from infection or other causes, not the object that is infected. Step 4: Examine option b, Body. The human or animal body is what becomes infected when germs invade. Step 5: Examine option c, Germs. Germs are the agents causing infection rather than the victim of infection. Step 6: Examine option d, Microbes. Microbes are tiny organisms like bacteria and viruses; they cause infection but are not what gets infected in the analogy. Step 7: Recognise that Body is the only option that stands in the same role as Food does in relation to contamination.

Verification / Alternative check:
Create parallel sentences. Contamination of food makes it unsafe. Infection of the body makes it ill. These sentences mirror each other closely. By contrast, contamination of germs or infection of microbes are meaningless, and contamination of diseases is also not logical. This confirms Body as the correct choice.

Why Other Options Are Wrong:
Diseases are outcomes rather than targets. Germs and microbes are causative agents. None of these are the object that becomes infected. The analogy requires a parallel between Food as an affected object and the entity similarly affected by infection, which is the Body.

Common Pitfalls:
Students may be tempted by Germs or Microbes because these words are heavily associated with infection. However, the pattern is not cause to cause but process to subject affected. Keeping track of that direction prevents these errors and points clearly to Body.

Final Answer:
The correct completion of the analogy is Infection : Body, just as Contamination : Food.
