The author most likely mentions that oxytocin and vasopressin are synthesized in the same place in
the brain and share most of their amino acid structure in order to
Correct!
[[snippet]]The author uses the similarities between the two hormones as a starting point for presenting the scientists' hypothesis about the splitting of vasotocin into two genes.
Incorrect.
[[snippet]]The passage states that although the two hormones are similar in structure, they nevertheless have completely different functions. Therefore, this couldn't be the author's intent in presenting this detail.
Incorrect.
[[snippet]]The passage tells us that the two hormones are created in the same place in the brain, yet they have completely different functions. Therefore, the place a hormone is created must not be crucial in determining its function, and the author would not promote such a view.
Incorrect.
[[snippet]]Although this sentence shows how oxytocin and vasopressin are similar, this is not the detail's purpose in the passage. The author uses their similarities to present an unlikely fact: despite their similarities, their functions are completely different.
Incorrect.
[[snippet]]Although the first sentence states that the two hormones reveal much about oxytocin’s evolutionary history, the claims regarding vasotocin are nonetheless a hypothesis made by scientists.
The author shows us that we can reveal much about oxytocin's evolutionary history, but does not describe an established history in the passage.
The similarities between oxytocin and vasopressin give scientists a reason to hypothesize that oxytocin comes from vasotocin, but this is only the theory of some scientists.
