Thinking...
We need to answer Yes or No, then explain in one sentence.
The logical statement: All A are B (A → B) and all B are C (B → C).
Therefore by transitivity A → C, so all A are definitely C. So answer Yes.
One-sentence explanation: Because if every A is a B and every B is a C, any
any A must also be a C.
Thus respond "Yes" then one sentence.
...done thinking.
Yes – since every A is a B and every B is a C, logically each A must also b
be a C.
