Biomass as fuel for power, heat and transport has very high mitigation potential among renewable sources. It comes from agricultural and forest residues as well as energy crops. The biggest challenge in using biomass residues is securing a long-term reliable supply at reasonable cost; logistics and collection costs are key problems. Energy crops, if not managed properly, compete with food production and may affect food prices. Biomass production is also sensitive to climate change. Projections of its future role may be overestimated because sustainable supply is limited unless technology greatly raises productivity. Some climate models rely on biomass-based carbon capture and storage, an unproven technology, to achieve negative emissions. Some liquid biofuels such as corn-based ethanol may aggravate rather than reduce lifecycle carbon emissions; second-generation lignocellulosic biofuels hold promise but remain under development.\n\nWith reference to the passage, the following assumptions have been made: 1. Some climate-energy models suggest biomass as fuel for power generation helps mitigate greenhouse-gas emissions. 2. It is not possible to use biomass as fuel without disrupting food and forest resources. Which assumption(s) is/are valid?2016 · Prelims CSAT · Reading Comprehension · Assumption
All humans digest mother's milk as infants, but until cattle began being domesticated about 10,000 years ago, children once weaned no longer needed to digest milk and stopped making much of the enzyme lactase. After humans began herding cattle, it became advantageous to digest milk, and lactose tolerance evolved independently among cattle herders in Europe, the Middle East and Africa. Groups not dependent on cattle, such as the Chinese and Thai, largely remained lactose intolerant.\n\nWhich among the following is the most logical assumption that can be made from the passage?2016 · Prelims CSAT · Reading Comprehension · Assumption
