A testable hypothesis is one that can be investigated through experimentation or observation, allowing for potential confirmation or disconfirmation based on evidence. Let's evaluate each statement you've provided:
1. **Plants produce glucose as the end product of photosynthesis.**
- This is a scientific fact rather than a hypothesis; it's well-established and therefore not a testable hypothesis in the context you're asking.
2. **Dropping a ball from a height of 10 m will cause it to bounce back up 5 m.**
- This is a testable hypothesis because you can drop a ball from a height of 10 m and measure how high it bounces back. You could confirm or reject this hypothesis based on the experimental outcome.
3. **If acid is added to a solution, then the pH of the solution will go down.**
- This is also a testable hypothesis. You can conduct an experiment by adding acid to a solution and measuring the pH before and after to see if it decreases, confirming or rejecting the hypothesis.
4. **If certain foods are healthy for you, then they should also taste good.**
- This statement is more subjective and involves personal taste preferences, making it less straightforward to test. While it could potentially be investigated through surveys or studies, it’s less clear-cut than the previous hypotheses.
In summary, the second and third statements are clearly testable hypotheses.

The most clearly testable hypothesis from your options is:
**If acid is added to a solution, then the pH of the solution will go down.**
This hypothesis can be tested through direct experimentation by measuring the pH before and after adding acid to the solution.
