While multiple web search results mention the P.D. Sirisena Stadium/Grounds in connection with the SJB May Day rally, the specific claim that it *will* be held there is reported by different sources with varying details (one mentions leaving the stadium, another mentions gathering near it). However, the evidence does not provide enough consistent, independent confirmation across multiple distinct sources to elevate the verdict beyond single_source, as the exact details (date, time, specific location) vary across the search snippets.

The web search results mention World Bank reports regarding poverty and global economics, but none of the retrieved snippets state the specific fact that 'one-third of the country's population has fallen below the poverty line.' The evidence is too general regarding World Bank reports on poverty to confirm this precise statistic.
