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: Physical activity level is associated with the difference in maximal oxygen consumption between black and white youth.

Abstract:
The purpose of this study was to examine differences in resting, submaximal, and maximal (VO2max) oxygen consumption (VO2) in African-American (n = 44) and Caucasian (n = 31) prepubertal children aged 5-10 yr.
Resting VO2 was measured via indirect calorimetry in the fasted state.
Submaximal VO2 and VO2max were determined during an all out, progressive treadmill exercise test appropriate for children.
Dual-energy X-ray absorptiometry was used to determine total fat mass (FM), soft lean tissue mass (LTM), and leg soft LTM.
Doubly labeled water was used to determine total energy expenditure (TEE) and activity energy expenditure (AEE).
A significant effect of ethnicity (P < 0.01) was found for VO2max but not resting or submaximal VO2, with African-American children having absolute VO2max approximately 15% lower than Caucasian children (1.21 +/- 0.032 vs. 1.43 +/-
0.031 l/min, respectively).
The lower VO2max persisted in African-American children after adjustment for soft LTM (1.23 +/- 0.025 vs. 1.39 +/-
0.031 l/min; P < 0.01), leg soft LTM (1.20 +/-
0.031 vs. 1.43 +/-
0.042 l/min; P < 0.01), and soft LTM and FM (1.23 +/-
0.025 vs. 1.39 +/-
0.031 l/min; P < 0.01).
The lower VO2max persisted also after adjustment for TEE (1.20 +/-
0.02 vs. 1.38 +/-
0.0028 l/min P < 0.001) and AEE (1.20 +/- 0.024 vs. 1.38 +/-
0.028 l/min; P < 0.001).
In conclusion, our data indicate that African-American and Caucasian children have similar rates of VO2 at rest and during submaximal exercise, but VO2max is approximately 15% lower in African-American children, independent of soft LTM, FM, leg LTM, TEE, and AEE.
