Step 1: Spot the direct statement.
In this kind of reading question, look for the sentence that explains the treatment. The author quotes the villagers' own words to explain it.
Step 2: Read what those words were.
The words say that he is a bachelor. This is the whole explanation offered in the text.
Step 3: Rule out the others.
Widower, orphan and a hated family member are all details that the passage does not contain. Choosing any of them would mean inventing facts.
Step 4: Link to the subject.
In the societies described, wives bring food gathered by women, so an unmarried man is at a disadvantage. This fits the economic role of marriage.
Step 5: Conclude.
Option 1 is the only choice supported by the text.
Final Answer:
Option 1, because he was a bachelor.
