Question

How is it possible that every man has a very good chance of obtaining a wife?

• A. Because the number of female births is double that of males.
• B. Because every man has the right to choose any one for marriage.
• C. Because there is biological equilibrium between male and female births.
• D. Because every woman has the right to choose any male as her mate.

Hint:

Option 3 is the cause, a balance of male and female births.

Answer 1

The Correct Option is C

Step 1: Find the idea in the passage.
The passage begins by saying that births of boys and girls are balanced in number. From this balance it draws the result that each man should have a good chance of finding a wife. The question asks for exactly this reason.

Step 2: Check option 1.
The passage never says girls are born in double the number of boys. It speaks of balance, not of double. So option 1 is wrong.

Step 3: Check option 2.
Nothing in the text talks about a man's right to pick any person. The reason given is about numbers, not rights. So option 2 is wrong.

Step 4: Check option 3.
This matches the opening idea of the passage, a balance between male and female births. Equal numbers mean every man can expect a partner. So option 3 is right.

Step 5: Check option 4.
The passage does not discuss a woman's right to choose a mate. It is also not the reason given for the chance of marriage. So option 4 is wrong.

Final Answer:
The reason given is the biological balance between male and female births, which is option 3.
