which statement best reflects a scientific statement?
o a today will be my lucky day because saturn rises in the north sky.
o b even if they survived the meteor crash, dinosaurs would still be extinct today.
o c it is going to rain today because my shoulder is tense.
o d my grass is growing very quickly because it has rained for three days in a row.

Explanation:

Question 9

• Option a: The composition of the Earth's atmosphere can be tested through scientific analysis (e.g., spectroscopy).
• Option b: The time it takes water to freeze can be experimentally measured (by controlling temperature and observing).
• Option c: The number of people in an earthquake - prone area can be statistically determined (through census data).
• Option d: The question "Should mining for phosphate be banned?" is a value - based (ethical, economic, etc.) question. Science can provide data on the environmental impacts of phosphate mining, but the "should" part is a matter of human judgment, not a testable scientific hypothesis.

• Option a: There is no scientific basis for Saturn rising in the north sky making it a "lucky day". It is a superstitious claim.
• Option b: While we can make inferences about dinosaur extinction, the statement "Even if they survived the meteor crash, dinosaurs would still be extinct today" is a speculative and not a well - supported scientific statement. There is no clear scientific evidence to back this up.
• Option c: There is no scientific connection between a shoulder being tense and it raining.
• Option d: There is a scientific relationship. Grass growth is related to water availability (rainfall). If it has rained for three days in a row, it can provide the necessary water for the grass to grow quickly, which can be tested (e.g., by comparing grass growth in areas with different rainfall amounts).

Answer:

d. Should mining for phosphate be banned?
