Application:** Imagine a popular health study is released claiming that eating apples significantly improves memory. How would this affect the demand curve for apples, and why?\n**4.

Answer:** The demand curve would shift to the right (increase). This is because a change in \"tastes\" or preferences (due to the health study) is a factor that shifts the entire curve.\n**4.
