Caitlin plans to conduct research to answer the question, "does loud music cause people to remember less of what they read? " which research method should she use to answer her question?

experiment                                              

Explanation:

Experiment: In psychology, the term experiment is defined as a method of investigation that underlies the hypothesis being scientifically tested.

In an experiment, generally, three different variables are being used including:

1. Dependent variable (the effect)- is measured.

2. Independent variable (the cause)- being manipulated or changed.

3. Extraneous variable- being controlled.

Advantage: An experiment needs to be objective.

In the question above, the given statement signifies the experiment.

question - in 1827, john walker, a druggist in a small english town, tipped a splint with sulphur, chlorate of potash, and sulphid of antimony, and rubbed it on sandpaper, and it burst into flame. the druggist had discovered the first friction-chemical match, the kind we use to-day. it is called friction-chemical because it is made by mixing certain chemicals together and rubbing them. although walker's match did not require the bottle of acid, nevertheless it was not a good one. it could be lighted only by hard rubbing, and it sputtered and threw fire in all directions. in a few years, however, phosphorus was substituted on the tip for antimony, and the change worked wonders. the match could now be lighted with very little rubbing, and it was no longer necessary to have sandpaper upon which to rub it. it would ignite when rubbed on any dry surface, and there was no longer any sputtering. this was the phosphorus match, the match with which we are so familiar. according the paragraph what was the benefit of the new phosphorus match? it burst into flame when rubbed on sandpaper. it was made by mixing chemicals. it could be ignited on any dry surface. it threw fire in all directions.

answer - matches required natural chemicals

the awnser is that is tru your

lol bye
