Analysis Summary:

The article's claim about hospitalizations due to the heatwave in North America is partially supported by available sources, but the specific number of people sickened at graduation ceremonies is not directly verifiable. The article exhibits a moderate level of bias due to selective reporting and potential exaggeration of the impact.

Detailed Analysis:

• Claim:** Dozens hospitalised as heatwave descends on North America.
  • Verification Source #1, #3: Both mention "Millions swelter as heatwave descends on North America," suggesting a widespread heatwave, but do not confirm hospitalizations.
  • Verification Source #4: Mentions an excessive heat warning in place for the Philadelphia area, northern Delaware, and nearly all of New Jersey, implying potential health risks.
  • Verification Source #2, #5: Do not cover this claim.
• Claim:** 150 people were sickened at outdoor graduation ceremonies in New Jersey due to the sweltering conditions.
• None of the provided sources directly confirm this specific claim. This claim is unverified.

Supporting Evidence/Contradictions:

• Verification Source #1, #3: Support the existence of a significant heatwave in North America.
• Verification Source #4: Supports the existence of dangerous temperatures in New Jersey, making it plausible that people could be sickened at outdoor events.
• None of the sources directly confirm the specific number of 150 people sickened at graduation ceremonies in New Jersey. This is a significant lack of coverage.
