Answer:
should be funneled by
Step-by-step explanation:
A thesis is the main idea or theory put forward by a writer and which he goes further to prove. A wordy thesis contains words or phrases that are not truly needed in the sentence because the thesis would still retain its meaning without those words.
In the thesis above, the wordy phrase is : "should be funneled by". This sentence would have been clearer if a smaller word is used that would not cloud the true meaning of the sentence.
