Question

in science, what does \classifying\ mean?
to identify or remove errors in data
arranging things into groups based on shared characteristics
to develop hypotheses and conduct experiments to test them
to make predictions about future events or observations

Explanation:

To determine the meaning of "classifying" in science, we analyze each option:

• The first option refers to data error handling, not classifying.
• The second option, "Arranging things into groups based on shared characteristics," matches the definition of classifying (e.g., taxonomic classification in biology, grouping elements by properties in chemistry).
• The third option describes the scientific method (hypothesis testing), not classifying.
• The fourth option is about prediction, not classification.

Answer:

B. Arranging things into groups based on shared characteristics
