2. Relevant - The article specifically discusses the biological methane and nitrous oxide emissions from livestock in New Zealand, which are significant contributors to greenhouse gas emissions.
3. Not relevant - The interview with senior citizens focuses on changes in the local air quality during their lifetime, but it does not necessarily address greenhouse gas emissions or their effect on New Zealand.
4. Not relevant - The essay contemplates punishment for farmers responsible for extra methane emissions, which is not directly related to the overall effect of greenhouse gas emissions in New Zealand.
