which one is better and whihc look human written

Question

These results emphasize the complex regulatory pathways involved in HbF generation and demonstrate the potential of CRISPR-Cas9 as a therapeutic tool for treating haemoglobin disorders. The discovery opens up new possibilities for gene therapy by showing that even small deletions in the BCL11A enhancer can effectively revert the switch from adult to foetal haemoglobin.

Answer 1

The second paragraph looks more human-written. It uses simpler language and sentence structure compared to the first paragraph. The use of "treatment" instead of "treating" and "reverse" instead of "revert" makes it easier to read and understand for a general audience.
