Question

qualitative observations
observations that are descriptive and involve using your senses to gather information
a testable prediction or educated guess; in the format of \if...then...\
factor being tested in an experiment that is changed by investigator; labeled on the x-axis
a statement about what will happen next in a sequence of events

Explanation:

The red box defines qualitative observations as descriptive, sense - based info - gathering. The orange is a hypothesis (testable “If…then…” guess). Green is the independent variable (changed by investigator, X - axis). Blue is a prediction (what happens next in events). To match "qualitative observations" definition: the red box's description ("observations that are descriptive and involve using your senses to gather information") is the correct match.

Answer:

The box with the text "observations that are descriptive and involve using your senses to gather information" (the red - colored box) is the one that defines qualitative observations.
