Final answer:
The logical conclusion is that a woman in New Mexico saw something bizarre in the sky and an older man disappeared on the same night.
Step-by-step explanation:
The logical conclusion based on the first two paragraphs of the passage is option C: A woman in New Mexico saw something bizarre in the sky last December, and on the same night, an older adult man disappeared. The passage describes how Pam Markesan saw three pulsing blue lights in the New Mexico sky and witnessed a spinning, disc-shaped craft.
Later that night, Alvin Mendez disappeared after being seen walking up a ramp into a giant, disc-like craft. This sequence of events suggests a connection between the sighting of the bizarre craft and the disappearance of Mr. Mendez, leading to the logical conclusion that something strange occurred in New Mexico last December.
