will be a decrease in demand as people buy less grapefruit.

will be a change in the price of oranges.
D.
cannot be determined because they have opposite effects on demand.
D. cannot be determined because they have opposite effects on demand.
B. People will buy less grapefruit because their tastes and preferences have changed.
To determine the answer to this question, we need to understand the cause and effect relationship described in the statement. According to the statement, medical research has shown that grapefruit juice can adversely affect the effectiveness of certain medications. This implies that consuming grapefruit juice while taking certain medications might reduce their effectiveness or pose potential health risks.
Based on this information, we can eliminate options C (people will buy less grapefruit because their incomes have increased) and D (the number of grapefruit sellers will decrease) as they are not logically connected to the cause and effect relationship described. The statement does not mention anything about people's incomes or the number of grapefruit sellers, so these options are incorrect.
Now let's consider options A and B. Option A states that the prices of oranges will change. However, the statement only provides information about grapefruit and its interaction with certain medications. There is no mention of oranges or any relationship between grapefruit and orange prices. Therefore, option A is also incorrect.
This leaves us with option B: people will buy fewer grapefruits because their tastes and preferences have changed. This option makes sense given the information provided. If people are aware of the negative interaction between grapefruit juice and certain medications, it is likely that their tastes and preferences might change, causing them to buy less grapefruit.
Therefore, the most likely answer is B: people will buy less grapefruit because their tastes and preferences have changed.
