Final answer:
The subject of this question is Critical Thinking. The correct answer is option A, as it weakens the argument by suggesting that other factors may have contributed to the increase in popcorn sales.
Step-by-step explanation:
The subject of this question is Critical Thinking since it requires analyzing the argument presented and identifying the statement that weakens it.
The claim made by the TheaterGoer is that the switch from canola oil to coconut oil has hurt popcorn sales. This claim is challenged by the fact that Megaplex sold 5% more popcorn last year than in the previous year, according to their own sales figures. To weaken the argument, we need to find a statement that contradicts or undermines this claim.
The correct answer is option A. If it is true that the total sales of all refreshments at Megaplex's movie theaters increased by less than 5 percent last year, then it suggests that the increase in popcorn sales may not be solely attributed to the switch in oil. Other factors could be contributing to the overall increase in sales.
