Question

does the following text have an inappropriate shift in verb tense? if so, fix any verbs that dont match the tense of the verb in bold. if not, submit the text without making any changes. in her chemistry demonstration, dakota showed that at sea level, water without impurities boils at 100°c.

Explanation:

The verb "showed" is in the past tense. However, the statement "water without impurities boils at 100°C" is a general scientific fact. General facts are stated in the present tense. So, there is no inappropriate shift in verb tense here. The past - tense verb "showed" is used to describe an action that Dakota did (the demonstration in the past), and the present - tense verb "boils" is used for the general fact about water's boiling point.

Answer:

In her chemistry demonstration, Dakota showed that at sea level, water without impurities boils at 100°C.
