Interpreting price trends across countries from 2015 to 2016

Steps:

• Examine Costa Rica's line: it rises from 2014 to 2015, then stays flat through 2016.
• Check India and Mauritius: both show increases from 2015 to 2016.
• Review Thailand and Japan: both lines rise from 2015 to 2016.
• Compare Costa Rica's 2015 and 2016 values: 2016 is higher than 2015, contradicting a decrease.

Why A is correct:

• The graph's line for Costa Rica slopes upward to 2015 (indicating a rise) and levels off in 2016 (indicating constancy), matching the trend definition of price movement.

Why the others are wrong:

• B: India and Mauritius lines slope upward from 2015 to 2016, showing higher prices.
• C: Thailand and Japan lines rise from 2015 to 2016, indicating higher prices.
• D: Costa Rica's line shows a higher value in 2016 than 2015, not lower.

Final answer: A
