qualitative observation
inference
quantitative observation
hypothesis

1. which of the following is an example of an inference

the boy is sad
the boy has only 9 fingers

Explanation:

To determine the type of statement "the worm is 2 cm long", we analyze the options:

• Qualitative observation describes qualities (e.g., color, texture), not numbers.
• Inference is a conclusion based on evidence, not a direct measurement.
• Quantitative observation involves numbers/measurements (like length in cm here).
• Hypothesis is a testable prediction, not an observation.

So the statement is a quantitative observation.

Answer:

C. quantitative observation (assuming the options are labeled A, B, C, D with C being "quantitative observation")
