Hello @errcamitchell @queenangel @baebrams and @aliktc,
There will be a live video explanation of this question during Office Hours this Friday, February 4 2022. If you miss it, you will be able to find the recording afterwards.
When thinking about this topic, I like to think about three different things: percentages, parts, and wholes. A "whole" can be anything — a whole population, an entire machine, a team, etc. I like to think of a "whole" pizza pie. "Percentages" refers to the proportion of the whole. So, did I eat half of the pizza? 1/4 of the pizza? 100% of the pizza? And the "parts" refers to the absolute value of the whole. So did I eat 6 ounces of pizza? A pound of pizza? Etc. (Substitute ounces/pounds for grams if you use the metric system, of course.) When we have information about two of those three things, we can usually make a deduction about the third. So if I told you I ate 50% of a pizza pie both yesterday and today (in other words, the "percentage" stayed the same), but yesterday I ordered a medium-sized pizza but today I ordered the larger jumbo-sized pizza (in other words, the "whole" increased), what could we conclude? That I ate more pizza today than yesterday (in other words, the "amount increased). Similarly, if I told you that both yesterday and today I ate a pound of pizza (part same), but yesterday I ate 50% of the pizza and today I ate 100% of the pizza (percentage increased), what could we conclude? Well, the pizza I ate today must be smaller (whole decreased). Here are some other common deductions, related to that: Part Increases Percentage Stays the Same C: Whole Increases Part Decreases Percentage Stays the Same C: Whole Decreases Percentage Increases Whole Stays the Same C: Part Increases Percentage Decreases Whole Stays the Same C: Part Decreases Whole Increases Percentage Stays the Same C: Part Increases Whole Decreases Percentage Stays the Same C: Part Decreases Whole Increases Part Stays the Same C: Percentage Decreases Whole Decreases Part Stays the Same C: Percentage Increases One of these applies to this question! (If you want a hint: "Marvel's market share decreasing" is the percentage, and the "Marvel's monthly sales remaining constant" is the part.) (If you want the answer, this is an example of: Percentage Decreases, Part Stays the Same, C: Whole Increases. So the total number of cars sold increased, which is why we can say (A) cannot be true.)

Is there a video explanation to this question readily avail yet..? I had trouble with this as well.
