Correlation and causation

Full solution

Q. Each of these relationships reflects a correlation. Which relationship most likely reflects both correlation and causation?

\newline

Choices:

\newline

(A) Eating plain yogurt more often is associated with better digestive health.

\newline

(B) Eating carrots more often is associated with drinking more carrot juice.

\newline

(C) Eating apples more often is associated with drinking water more often.

Analyze Relationship (A): Analyze the relationship of the first option (A): Does eating plain yogurt cause better digestive health? There is a plausible biological mechanism where probiotics in yogurt can improve gut flora, which is associated with better digestive health. This suggests a potential causative relationship.
Analyze Relationship (B): Analyze the relationship of the second option (B): Does eating carrots cause an increase in drinking carrot juice? While there is a correlation, the causation is not direct. People who eat carrots may also like carrot juice, but eating carrots doesn't cause one to drink carrot juice.
Analyze Relationship (C): Analyze the relationship of the third option (C): Does eating apples cause an increase in water consumption? It's unlikely that there is a direct causative relationship. People may drink water for hydration after eating apples due to the fruit's fiber content, but this is a weak causal link compared to option (A).
Select Most Plausible Option: Select the option that most likely reflects both correlation and causation. Based on the analysis, option (A) 'Eating plain yogurt more often is associated with better digestive health' is the most plausible relationship that reflects both correlation and causation.

A large truck, traveling

30

miles per hour, carries a letter from the central post office to the local post office. The letter is then loaded onto a local vehicle, which travels at an average speed of

10

miles per hour, until the letter reaches its destination. The large truck carried the letter for

a

minutes and the local vehicle carried the letter for

b

minutes. If the total distance that the letter travelled from the central post office to its destination was

24

miles, which of the following equations correctly relates

a

b

\newline

\newline

\frac{30}{60} a+\frac{10}{60} b=24

\newline

\frac{60}{30} a+\frac{60}{10} b=24
