How did Galileo's hypothesis most likely help with the development of this new technology?  
 (A) by leading Galileo to design a different technology (B) by allowing another scientist to critique Galileo's hypothesis (C) by providing evidence of the effects of atmospheric pressure (D) by inspiring another scientist to test an alternative hypothesis

Output: D
