For a certain community, the graph shows the total number of new homes built in each of the last 15 years. The annual change in the number of new homes built for a given year is the total number of homes built that year minus the total number of homes built in the previous year.

Select from the drop-down menus the options that create the statement that most accurately reflects the information provided.

Among the Years 2-15, the first year for which the annual change in the number of new homes built was negative was Year , and that year was immediately followed by exactly consecutive years for which the annual change in the number of new homes built was positive.

Show Spoiler


You're trying to find out the annual change that is less than the year prior. The first instance where this is shown is in year 8 where the number of new homes built is closer to 800 while in year 7, it's closer to 900. This then follows a period where year 9-13 have increases and then another decrease in year 14.

Great! Thank you very much. This means the source is GMAT Prep Focus. The Official Guide refers to the physical or online books, while GMAT Prep Focus refers to the official GMAT Prep mocks. When posting such questions, it's always helpful to attach a screenshot.

Bunuel, why is the answer to the second drop-down not 6?
Years 2, 3, 4, 5, 6, and 7 had a positive annual change, right? Or is it the case that since we are considering only years 2-15 in the question, we can't determine the change for Year 2?

You're missing the key part: "immediately followed by exactly".

Year 8 is the first with a negative change. After that, the number of homes increased for 5 years: Years 9, 10, 11, 12, and 13. In Year 14, the number drops again, so the streak ends there.

That's why it's Year 8, followed by exactly 5 consecutive years of positive change.
