Recent advances in organ transplant methods have included a [#permalink] New post 14 Apr 2019, 10:37
Expert's post
Recent advances in organ transplant methods have included a resurgence in interest in xenotransplantation— any procedure in which the transplant materials are taken from a non-human source— due to its potential to eliminate any issues related to scarcity in the availability of human organs for transplant.   Scientific interest in using organic material from non-human sources to improve health, and even stave off death, is certainly not new. Anecdotal evidence of humans’ attempts to transplant limbs from animals in order to achieve superhuman feats, both successful and unsuccessful, has existed since ancient times and is deeply woven into Greek mythology. The early 19th century included more forays into the potential for non-human primate organs to be used for human transplantation, though from a scientific perspective, the record of success left much to be desired.   Work in this field has not been without its critics,   as animal welfare groups have spoken about the concerns of genetically modifying animals for the sole purpose of organ harvesting and the long-term consequences of ignoring the ethical implications for much of the xenotransplantation timeline.   Whether society ultimately decides the potential benefits to humans in need of organ transplants outweigh the possible exploitation of thousands of animals remains to be seen.
In the passage above, what roles do the highlighted sentences serve?

1) The first sentence is the main idea, and the second sentence restates the main idea.
2)The first sentence makes the central argument of the passage, and the second sentence provides a supporting example.
3) The first sentence is an example, and the second sentence is the author’s conclusion.
4) The first sentence is an explanation, and the second sentence is an analysis of that explanation.
5) The first sentence introduces the topic, and the second sentence presents a criticism.
