You will be shown a scientific claim, 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". If the abstract does not provide enough information to arrive at a verdict, write "NEI" (for "not enough information").
- "evidence": An array of sentences providing evidence for the verdict. Please copy all relevant sentences verbatim from the abstract. If the verdict was "NEI", then return an empty array.

For instance, if the model were given the claim "smoking causes cancer", the output might be
{
  "verdict": "SUPPORT",
  "evidence": ["The results of our meta-analysis provide overwhelming support that cigarette smoking is a risk cause for lung cancer."]
}

Your response should not include any text other than the json.

Claim: ScPif1p has reduced binding ability to G-rich ssDNA compared to non-G-rich ssDNA.

Abstract:
The Saccharomyces cerevisiae Pif1 helicase is the prototypical member of the Pif1 DNA helicase family, which is conserved from bacteria to humans.
Here we show that exceptionally potent G-quadruplex unwinding is conserved among Pif1 helicases.
Moreover, Pif1 helicases from organisms separated by more than 3 billion years of evolution suppressed DNA damage at G-quadruplex motifs in yeast.
The G-quadruplex-induced damage generated in the absence of Pif1 helicases led to new genetic and epigenetic changes.
Furthermore, when expressed in yeast, human PIF1 suppressed both G-quadruplex-associated DNA damage and telomere lengthening.
