Is it true or false that composers are mostly concerned with pitch and are less concerned with rhythm?

The question is asking to choose if the said statement is true or false that composers are mostly concerned with pitch and are less concerned with rhythm, base on my research and further investigation, I would say that the answer would be False. I hope you are satisfied with my answer 

False

Explanation:

As rhythm makes a music move with the flow and it makes up the sound and silences and pitch is the intensity or the quality of the sound that is governed by the rate of the tone. Thus both are important as pitch without rhythm cannot exist.
