“The 190.08-carat diamond, unearthed at the Vladimir Grib deposit in the Arkhangelsk Region, was discovered at a depth of 375 meters”
SINGLE SOURCE
The TASS search result title mentions a 190-carat diamond at a depth of 375m, but the provided snippet for that specific source is actually the evidence for Claim 2. The evidence provided for Claim 0 consists of Mercedes-Benz cars, which is irrelevant. However, looking at the evidence provided for Claim 2, the TASS headline confirms the 190-carat diamond and 375m depth. Since only one news organization (TASS) is providing this specific detail in the snippets, it is a single source.
