You will be shown a claim related to the COVID-19 pandemic, and the abstract of a biomedical research paper. Each sentence from the abstract will be on a separate line. Your task is to return a JSON object with two fields:

- "verdict": The fact-checking verdict. If the information in the abstract supports the claim, write "SUPPORT". If the abstract contradicts the claim, write "CONTRADICT".
- "evidence": An array of sentences providing evidence for the verdict. Please copy all relevant sentences verbatim from the abstract.

For instance, if the model were given the claim "the COVID vaccine is safe for healthy adults", the output might be
{
  "verdict": "SUPPORT",
  "evidence": ["Our findings indicate that the risks of severe COVID vaccine side effects are low for healthy adults."]
}

Claim: Sars-cov-2 genome evolution exposes early genes adaptations

Abstract:
The set of mutations observed at the outset of the SARS-CoV-2 pandemic may illuminate how the virus will adapt to humans as it continues to spread.
Viruses are expected to quickly acquire beneficial mutations upon jumping to a new host species.
Advantageous nucleotide substitutions can be identified by their parallel occurrence in multiple independent lineages and are likely to result in changes to protein sequences.
Here we show that SARS-CoV-2 is acquiring mutations more slowly than expected for neutral evolution, suggesting purifying selection is the dominant mode of evolution during the initial phase of the pandemic.
However, several parallel mutations arose in multiple independent lineages and may provide a fitness advantage over the ancestral genome.
We propose plausible reasons for several of the most frequent mutations.
The absence of mutations in other genome regions suggests essential components of SARS-CoV-2 that could be the target of drug development.
Overall this study provides genomic insights into how SARS-CoV-2 has adapted and will continue to adapt to humans.
SUMMARY In this study we sought signals of evolution to identify how the SARS-CoV-2 genome has adapted at the outset of the COVID-19 pandemic.
We find that the genome is largely undergoing purifying selection that maintains its ancestral sequence.
However, we identified multiple positions on the genome that appear to confer an adaptive advantage based on their repeated evolution in independent lineages.
This information indicates how SARS-CoV-2 will evolve as it diversifies in an increasing number of hosts.
