Solution
To determine the most logical and precise word or phrase to complete the text, let's analyze the context and the meaning of each option:
-
Indeterminate: This means not exactly known, established, or defined. It fits well because it suggests that scientists did not have a clear understanding of how much Neanderthal genes inform human traits.
-
Confounding: This means causing confusion or surprise. It doesn't fit well in this context because it doesn't relate to the clarity or certainty of the hypothesis.
-
Meticulous: This means showing great attention to detail. It doesn't fit well because it doesn't relate to the certainty or clarity of the hypothesis.
-
Conventional: This means based on or in accordance with what is generally done or believed. It could fit, but it doesn't convey the same sense of uncertainty as "indeterminate."
Given the context, the best choice is:
Indeterminate
So, the completed text would be:
"Recent research has discovered that the Neanderthal DNA makes up as much as 1-4% of the genome of present-day humans. However, scientists only had indeterminate hypothesis about how much those genes inform human traits until a new study out of the UK looking at gene expression in people with European descent who have the most likelihood of Neanderthal lineage.

Modern groups that are likely to have DNA from Neanderthals
Neanderthals and humans have had a long and intertwined history. Studies of ancient DNA have shown that human and Neanderthal lineages split apart 700,000 years ago. However, fragments of Neanderthal DNA can still be found in living humans. John Capra, a geneticist at University of California San Francisco, has been researching the remaining fragments of Neanderthal genes as they relate to sleep. Capra found evidence that the age old question of whether someone is an early riser or a night owl can be answered by studying Neanderthal fragments in DNA: people who were early risers had more Neanderthal fragments in their DNA than people who preferred staying up late.Which choice best describes the function of the fourth sentence in the overall structure of the text?It makes a generalization about the presence of Neanderthal fragments in modern human DNA.eliminateIt introduces a certain study related to the general information cited earlier about the connection between human and Neanderthal DNA.eliminateIt offers a specific example of the link between sleep and fragments of Neanderthal DNA found in modern humans.eliminate It states the hypothesis investigated by geneticist John Capra and his team at the University of California San Fransisco.
