The thing that would mostly make the results of the experiment invalid would be the students themselves. No one is built the same, and the exact same food can have very different effects on different people.

Hello. This question is incomplete, answer options are missing. The options are:

"a)Half of the students ride the bus to school, and half ride in cars.  b)Some students eat breakfast two hours before other students do.  c)Some students miss school during the investigation due to illness.  d)All students in the investigation have morning classes in the same subjects."

Answer:

b)Some students eat breakfast two hours before other students do.

Explanation:

In a scientific experiment like the one shown in the question above, it is essential that students show no variation in the times they eat. This is because any variation would lead to differences in the digestion of each student and would result in an inaccurate and unreliable result.

More fully explained, we can say that if some students ate two hours before other students, the research could be invalid. This is because students would have different stages of digestion and this would not allow them to evaluate the effects of eating different breakfast foods on morning class notes.
