Creating a database of all the plant species in the scientific record is not easy. For centuries, botanists have been naming plants without realizing that some were already named. Moreover, by using DNA analysis, botanists have shown that varieties of plants long thought to belong to the same species actually belong to different species.

DNA analysis could inform botanists whether a plant species has been named.

Could be true. The stimulus does not give us any information about the total number of duplicates and omissions in the scientific record. It is possible that most of these errors have not yet been fixed.

Could be true. There is no information in the stimulus that contradicts the idea that an accurate database would be helpful.

Could be true. The information in the stimulus is restricted to botany. It is possible that the same or similar errors occur in other fields.

Must be false. The stimulus tells us that DNA analysis has shown what plants belong to what species. Therefore, DNA analysis is a technique that botanists could use to determine whether a plant species has been given a distinct name.

Could be true. The stimulus tells us that botanists have been naming plants without realizing that some plants have already been named. If this is true, then it is possible that some information about the same plant is just associated with a different name.
