A body paragraph must be arranged with a reason supported by evidence. The words that can complete the sentence are "found evidence" and "present." The best way to rewrite the sentence is "Biotechnology has many benefits. However, the risks outweigh the benefits."
We can arrive at these answers because:
Evidence should be used in a paragraph to substantiate an argument, though, or reason presented.
Every paragraph needs to obtain this reason, which will be accompanied by the evidence.
An example of this can be seen when scientists find chemical substances present in drinking water and need to prove that these substances exist within a text. This proof is made through the evidences.
When we are writing and we want to present two pieces of information, where one contests some element of the other, we must present a word that represents this context to link the two pieces of information. That word could be "However."
With this, we can see the importance of knowing how to correctly structure a paragraph to promote a good text.
