Everyone in mrs. blaylock's science class must perform an experiment for the science fair this year. to begin this process, mrs. blaylock asks her students to brainstorm four different questions that they could study.

one of mrs. blaylock's students writes down the following questions.
how does the mass of a toy car affect its speed down a ramp?

how does the position of the sun, moons, planets and stars affect a person's personality traits and daily behavior patterns?

which type of pan - copper, aluminum, or glass - heats up the quickest?

which type of chemicals can remove the cell wall of a plant cell?
which of the above questions cannot be answered through a scientific investigation?

Explanation:

Science or scientific investigations deal with objective phenomena; this is phenomena which can be described by using objective measurements.

The effect of the position of the Sun, moons, planets and stars on a person's personality and daily behavior patterns is not a scientific question because none scientific field deals with that kind of questions.

Only, a pseudoscience, this is a set of beliefs that have not been scientifically proved, may deal with a question about the effect of the position of some heavenly objects can affect a person's personality traits and daily behavior of patterns.

On the other hand, the aspects deal with in the other questions (the mass of a toy car, the speed down a ramp, the heating from different type of pans, how different type of chemicals remove the cell wall of a plant cell) are measurable and testable (falsifiable), which make them objects of science (like physics, chemistry, and biology)

the correct answer to this question is 2
