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: Locate the claim.
Read the first two sentences of the passage. The first states a fact about births. The second begins with the word Consequently, which marks the man's chance of marriage as a result of that fact.

Step 2: Name the cause.
The cause before Consequently is a natural balance between male and female births. So the answer must restate that balance in other words.

Step 3: Test options 2 and 4.
Options 2 and 4 speak of rights to choose a partner, which the passage never mentions. They cannot be the cause of anything the author says.

Step 4: Test option 1.
Option 1 speaks of double female births, which is an imbalance, the opposite of the stated fact. So it fails too.

Step 5: Test option 3 and conclude.
Only option 3 repeats the balance between male and female births, so it is the one cause named in the text.

Final Answer:
Every man has a good chance of marriage because male and female births are balanced. \[\boxed{\text{Option 3}}\]
