Identify the correct option regarding the given statements and conclusions:
Statements:

1. All swans are fishes.
2. All fishes are crabs.

Conclusions:

1. All swans are crabs.
2. Some crabs are swans.

From the statements, we can draw a Venn diagram relationships:
* Statement 1 implies $\text{Swans}\subseteq \text{Fishes}$.
* Statement 2 implies $\text{Fishes}\subseteq \text{Crabs}$.

Combining them gives $\text{Swans}\subseteq \text{Fishes}\subseteq \text{Crabs}$, which means all swans are inside the set of crabs.

* Conclusion 1 ("All swans are crabs") must be true.
* Conclusion 2 ("Some crabs are swans") must be true because the region belonging to swans is also part of crabs.
Thus, both conclusions follow.
