Part A: Which of the following best summarizes this article? *
A group of scientists recently generated embryonic stem cells through cloning, which may help cure many diseases, though the process raises serious ethical concerns.
Stem cell research has long been hindered by controversy and repeated attempts to publish falsified data and experiments.
The most powerful criticism of stem cell research revolves around the fact that it necessarily and universally involves destroying human embryos.
Several scientists have already begun attempting to generate living human clones, and the generation of embryonic stem cells provides a vital stepping-stone to their efforts.
