Logical reasoning:
a. Some women are smart.
b. All smart women are good looking.
c. Monika is a woman.
d. Monika is smart.
e. Monika is good looking.
f. All women are good looking.

Choose the valid sequence of statements that forms a logically sound argument:

Let us evaluate the options to check for a valid syllogistic deduction structure (Premise 1 + Premise 2 $⟹$ Conclusion):
* Consider option B) bde:
* Statement b (Major Premise): All smart women are good looking.
* Statement d (Minor Premise): Monika is smart (and a woman).
* Statement e (Conclusion): Therefore, Monika is good looking.
This follows the classic valid deductive form: $\text{All }M\text{ are }P$; $S\text{ is }M$; therefore, $S\text{ is }P$. Thus, bde is a logically valid sequence.
