  1. A. Soil tests measured a pH of 5.2 in the north bed and 6.8 in the south bed.Correct
  2. B. The north bed gets less sun.
  3. C. Both beds were dug in the same year.
  4. D. The south bed is larger.

Answer: A. Soil tests measured a pH of 5.2 in the north bed and 6.8 in the south bed.

A lower pH means more acidic, and 5.2 is lower than 6.8.

B. The north bed gets less sun.
Sunlight doesn't measure acidity.
C. Both beds were dug in the same year.
Age doesn't bear on acidity.
D. The south bed is larger.
Size doesn't bear on acidity.
