Official Solution:
Statement 1
A direct correlation means that as one variable increases, the other also increases, or as one decreases, the other decreases—they move in the same direction. Between 2005 and 2010, the number of domestic non-revenue flights followed the pattern: down, down, up, down, down. During the same period, the total number of domestic flights followed a different pattern: up, up, down, down, down. Clearly, there is no direct correlation between these numbers. Therefore, this statement is False.
Statement 2
The greatest decrease occurred in International Charter flights, which dropped from 1,266 to 188—a decrease of approximately 85%. The greatest increase occurred in International Commuter flights, which rose from 5,209 to 7,714—an increase of approximately 50%. Therefore, this statement is True.
Statement 3
In 2005, the number of international cargo flights was 14,380, while the combined total of all international and domestic flights was 119,706 + 230,242 ≈ 350,000. Clearly, 14,380 is less than 10% of 350,000. Therefore, this statement is False.
Correct answer:
From 2005 to 2010, there was a direct correlation between the number of domestic non-revenue flights and the total number of domestic flights. "False"
The largest percentage decrease in flights for any category from 2005 to 2010 is greater than the largest percentage increase in flights for any category from 2005 to 2010. "True"
In 2005, international cargo flights represented more than 10% of the total number of international and domestic flights combined. "False"

regarding question number 2.
When you say category, it means within domestic or international right?
like the change in domestic cargo in year X vs domestic cargo in year X+n and Not any type of cargo in subsequent years.
So when I compare I should have sorted year first then sorted domestic/international. after that should start analyzing.
