A is the answer bc it is refering to another objet inthis case it could be the ggese
<span>For a living organism to exist it needs to feed off of something to live. The basic eco cycle of life. If there is no food supply it ceases to exist and dies. This also could define other things in the world that are not organisms, like a rock.</span>
In this sentence :
"You also learn what it takes to make money: a lot of effort.”
The main verb is "learn". The verb Takes is also a verb but since it is within the next clause and it is the verb of the Cataphoric refrence "it" such verb cannot be considered the main verb of the sentence.
So your final aswer is Learn.
I'm almost positive the answer is: "It will help organize the flow of ideas". I hope I helped! :)
