The experiment that produces the most reliable results is the one in which the
a. hypothesis is proved
b. first hypothesis was changed
c. results are repeatable
d. latest equipment was used

I think for the experiment to be reliable, it must be repeated certain amount of times, roughly as many as you can, it doesnt matter whether the hypothesis is right or wrong. If the experiment is repeatedly reliable, the hypothesis might be correct.

You should provide a picture to show where the arrow is pointing and which information that is given. but there are 3 branches of the government, legislative, executive, and judicial. legislative makes laws, executives pass laws, and judicial are the courts
