What’s the answer to this question
**Critical Thinking Exercise: Analyzing Correlations and Causations in Research**

**Question 2 of 10**
 
Suppose a report stated the following:
 
Researchers have found a strong connection between the amount of money a person spends on bookshelves and that person’s level of literacy. Therefore, they recommend buying more bookshelves to increase literacy.

**Question:**
Why is the researchers' conclusion likely incorrect?

**Multiple Choice Options:**

- **A.** Buying bookshelves, not reading books, results in better literacy.
- **B.** Reading books, not buying bookshelves, results in better literacy.
- **C.** The amount of money a person spends on bookshelves is correlated with literacy level.
- **D.** The number of books a person reads is correlated with literacy level.
 
**Analysis:**
The primary concern with the researchers' conclusion is that it may confuse correlation with causation. The observed correlation between the money spent on bookshelves and literacy levels does not imply that buying bookshelves causes increased literacy. Other variables, such as the reading habits and the number of books a person owns, are more directly linked to literacy. Consequently, the most plausible answer is likely related to the actual causative factors contributing to literacy, rather than the mere purchase of bookshelves.

**Correct Answer:**
- **B.** Reading books, not buying bookshelves, results in better literacy. 

This exercise emphasizes the importance of critically analyzing research findings and understanding the difference between correlation and causation in educational research.
