Goiter : Non-communicable :: Conjunctivitis : ________

Answer

To solve the analogy "Goiter : Non-communicable :: Conjunctivitis : ________", we will analyze the relationship between the first pair of terms and then apply that understanding to the second pair.

### Step-by-Step Solution:

1. **Understand the First Term (Goiter)**:
- Goiter is a condition characterized by an enlargement of the thyroid gland, often due to iodine deficiency.
- It is classified as a **non-communicable disease**, meaning it cannot be transmitted from one person to another.

2. **Understand the Second Term (Conjunctivitis)**:
- Conjunctivitis, also known as pink eye, is an inflammation or infection of the conjunctiva (the membrane covering the white part of the eye).
- This condition can be caused by bacteria, viruses, or allergens and is often spread through direct contact with infected eye discharge or contaminated surfaces.

3. **Identify the Relationship**:
- The relationship in the first pair is that Goiter is a non-communicable disease.
- Therefore, we need to find out what type of disease Conjunctivitis is.

4. **Determine the Classification of Conjunctivitis**:
- Since conjunctivitis can be transmitted from one person to another (through contact), it is classified as a **communicable disease**.

5. **Complete the Analogy**:
- Based on the analysis, we can conclude that:
- Goiter is to non-communicable as conjunctivitis is to communicable.

### Final Answer:
Conjunctivitis : Communicable
