Question

this lab shows how scientific explanations are only ________ explanations, because new discoveries may show that previous explanations were incorrect.

○ reliable

○ absolute

○ very mindful

○ tentative

Explanation:

To solve this, we analyze each option:

• "reliable" implies consistency, but the context says previous explanations can be incorrect, so not reliable.
• "absolute" means unchanging, but new discoveries change explanations, so not absolute.
• "very mindful" is about awareness, not related to scientific explanations' nature.
• "tentative" means provisional, as new discoveries can correct previous ones, so scientific explanations are tentative.

Answer:

D. tentative
