(1 point) the cost of the new fertilizer compared to the old fertilizer the weekly rainfall for a month the temperature each day for a few weeks the height of each corn plant each day for a few weeks

Explanation:

To determine the effect of fertilizer on corn growth, we need data related to the corn plants' growth. The cost of fertilizer (first option) is about cost, not growth. Weekly rainfall (second) and daily temperature (third) are environmental factors, not direct measures of corn growth. Measuring the height of each corn plant daily (fourth) directly relates to growth, allowing comparison between fertilized and unfertilized plants.

Answer:

D. the height of each corn plant each day for a few weeks
