A strong correlation between two variables means that as one variable changes, the other variable tends to change in a consistent and predictable way. In the scenarios provided:
A: Price of coffee and price of computers - These are likely to have a weak or nonexistent correlation, as these two variables do not directly influence each other.
B: Oil prices and airfare prices - This is likely to represent a stronger correlation. Typically, as oil prices increase, airfare prices may also increase since fuel is a major cost for airlines.
C: Increase in spending and increased ability in being able to make cheese - This scenario is unclear and context-dependent. While spending might influence production capabilities, it doesn't directly imply a strong, consistent relationship without more context.
Based on these analyses, **B: oil prices and airfare prices** represents a strong correlation.
