Two teams sequenced the same Neanderthal finger bone and disagreed about how much of the genome was contamination from the people who handled it. The Leipzig group treated any fragment matching a modern European haplotype as suspect and discarded a tenth of its reads. ______, the Uppsala group kept every fragment and modelled contamination as a rate to be estimated afterwards, which left more data and a wider error bar around every result.
Which choice completes the text with the most logical transition?
- A) In contrast, ✓
- B) For instance,
- C) Likewise,
- D) Consequently,
Why: One team threw out suspect reads and the other kept them all, so a contrasting transition is needed. Result invents causation between two independent teams, and likeness and illustration both treat the second method as a version of the first. Consequently, is result, and the Leipzig method did not cause the Uppsala one. Likewise, is likeness, though discarding reads and keeping them are opposite choices. For instance, is illustration, which would make the Uppsala approach an instance of the Leipzig one.
