Question

The number of years in which there was an increase in revenue from at least two categories is

• A. 1
• B. 2
• C. 3
• D. 4

Hint:

For "at least two categories increased," check each year-to-year transition and tally the rises per category; count a year when the tally is $\ge 2$.

Answer 1

The Correct Option is B

Compare each consecutive pair of years and count how many categories (Journals, Magazines, Books) increase in that transition. From the bars, there are two such transitions where at least two categories rise, hence the count is \(2\). \[ \boxed{2} \]

Answer 2

This can also be worked out by building a small increase/decrease table across each pair of consecutive years and tallying how many categories rise in each transition, rather than scanning the bars informally.

Building the tally. For each year-to-year transition, mark whether Journals, Magazines, and Books individually increased (+) or not. A transition "qualifies" only if at least two of the three categories show a plus.

Counting qualifying transitions. Going through the chart's consecutive year-pairs this way, exactly two transitions have two or more categories rising together, while the remaining transitions have at most one category increasing.

1. Option 1: Too low — more than one transition in the chart shows at least two rising categories; ruled out.
2. Option 2: Matches the tally — exactly two transitions qualify.
3. Option 3: Too high — one of the transitions counted this way only has a single category rising, not two; ruled out.
4. Option 4: Far too high given how few transitions show broad-based increases across the years shown; ruled out.

The tally method confirms that only two of the year-to-year transitions have at least two of the three categories increasing simultaneously.

So the correct answer is 2.
