change 2 of the non-testable questions to testable questions in the space.

Explanation:

To solve this, we first identify non - testable questions (subjective or unmeasurable) and rephrase them to be testable (measurable, objective, with variables).

Step 1: Identify non - testable questions

• Question 5: "Which planet is the most interesting one to study?" (Interest is subjective)
• Question 8: "Do larger or smaller seeds make prettier flowers?" (Prettiness is subjective)
• Question 9: "Do flying saucers really exist?" (Existence of flying saucers is hard to test directly in a scientific way with standard methods)
• Question 11: "Why does doing homework help your grades?" (Asks for a reason, not directly testable, but can be rephrased)

Step 2: Rephrase non - testable to testable (choosing two)

For Question 5:

Original: Which planet is the most interesting one to study?
Testable rephrase: Which planet has the most number of known moons (a measurable quantity) among the planets in our solar system?

For Question 8:

Original: Do larger or smaller seeds make prettier flowers?
Testable rephrase: Do larger or smaller seeds produce flowers with a greater diameter (a measurable aspect related to flower size, which can be an objective measure instead of "prettier")?

Final Answer (two rephrased testable questions)

1. Which planet has the most number of known moons among the planets in our solar system?
2. Do larger or smaller seeds produce flowers with a greater diameter?
