Final answer:
An observation that the student could have made without making an inference is the size of the leaves produced by plant X.
Step-by-step explanation:
An observation that the student could have made without making an inference is:
- The leaves produced by plant X are 4 cm across and 8 cm in length.
An inference, on the other hand, would involve making a conclusion based on the observation. For example, if the student observed that plant X produces many seeds that are highly attractive to finches, it would be an inference to conclude that the plant has evolved this trait to attract birds for pollination.
