In late 2018, Chinese researchers led by He Jiankui announced that they had used CRISPR-Cas9 to genetically modify human embryos, which were then transferred to a woman's uterus and resulted in the birth of twin girls-the first gene-edited babies. The twins' genomes were modified to make the girls more resistant to HIV, although the genetic alterations may have also resulted in unintended changes. A major concern has been that the team's attempts to cripple the gene for a protein on immune cells that HIV uses to infect the cells, also made "off-target" changes elsewhere in the girls' genomes. Those changes could cause cancer or other problems. The work was _______________16Mark for ReviewABCWhich choice most logically completes the text?Ashort on potential complication of editing, paying much less attention than on off-target edits.Bdismissed by other researchers, who pointed to conflicting epidemiologic analyses.Cwidely condemned by the scientific community as unethical and dangerous.Dnot updated on the health of the children, and the outcome, perhaps may never be headline news.

1. The discovery has opened new avenues for research and potential treatments for various diseases.2. The ethical implications and potential risks of such technologies, notwithstanding their benefits, need careful consideration.3. Advances in genetic engineering, such as CRISPR-Cas9, have enabled precise manipulation of DNA sequences.4. Scientists can now potentially correct genetic mutations, prevent hereditary conditions, and even engineer more resilient crops.
