According to 'Rivet Popper Hypothesis', the airplane will become dangerously weak if

Options

A. More rivets are added to the air plane
B. Popping of rivets continue
C. Passengers start moving
D. Few rivets exchange their positions

Answer

### Step-by-Step Solution:

1. **Understanding the Rivet Popper Hypothesis**: The Rivet Popper Hypothesis was proposed by L. Rich in 1981. It draws an analogy between an airplane and an ecosystem, suggesting that just as an airplane relies on rivets for structural integrity, an ecosystem relies on species for its stability.

2. **Identifying the Components**: In this analogy, the airplane represents the ecosystem, and the rivets represent the species within that ecosystem. Each rivet (species) contributes to the overall strength and functionality of the airplane (ecosystem).

3. **Analyzing the Impact of Rivet Loss**: According to the hypothesis, if rivets (species) are lost or damaged, the airplane (ecosystem) becomes dangerously weak. This is because the loss of rivets compromises the structural integrity of the airplane, similar to how the loss of species can destabilize an ecosystem.

4. **Considering the Options**:
- **More rivets are added**: This would not weaken the airplane; rather, it would strengthen it.
- **Popping of rivets continues**: This means rivets are falling off, which would indeed weaken the airplane and disrupt the ecosystem.
- **Passengers start moving**: This is related to migration and does not necessarily weaken the airplane or ecosystem.
- **A few rivets exchange their position**: This change does not harm the airplane or ecosystem.

5. **Conclusion**: The airplane will become dangerously weak if the "popping of rivets continues," as this directly correlates to the loss of species in an ecosystem, leading to instability and potential collapse.

### Final Answer:
According to the 'Rivet Popper Hypothesis', the airplane will become dangerously weak if the popping of rivets continues.
