Fan : Sweat :: ?: ?

Options

A. Fire : Smoke
B. Rain : Drought
C. Wind : Evaporation
D. Crop : Harvest

Explanation

To solve the analogy "Fan : Sweat :: ?: ?", we need to identify the relationship between the first pair (fan and sweat) and apply that same relationship to find the second pair.

### Step-by-Step Solution:

1. **Identify the Relationship**:
- A fan is used to cool down a person and reduce sweat. Thus, the relationship is that a fan helps to alleviate or eliminate the discomfort caused by sweat.

2. **Analyze the Options**:
- **Option 1: Fire and Smoke** - Fire produces smoke, but it does not help to eliminate it. This does not match the relationship.
- **Option 2: Rain and Drought** - Rain helps to alleviate drought conditions by providing water. This matches the relationship since rain helps to eliminate the discomfort caused by drought.
- **Option 3: Wind and Evaporation** - Wind does not help to eliminate evaporation; rather, it can increase it. This does not match the relationship.
- **Option 4: Crop and Harvest** - Crops are grown to be harvested, but they do not help to eliminate the concept of harvest. This does not match the relationship.

3. **Select the Correct Option**:
- After analyzing all the options, we find that **Option 2 (Rain and Drought)** is the only pair that maintains the same relationship as "Fan : Sweat".

### Final Answer:
The answer is **Rain : Drought**.
