QUES: Later the same month, Barcelona won the UEFA Super Cup after defeating Porto 20 thanks to goals from Lionel Messi and Cesc Fabregas. This extended the club's overall number of official trophies to 74, surpassing Real Madrid's total amount of official trophies. The UEFA Super Cup victory also marked another impressive achievement as Josep Guardiola won his 12th trophy out of 15 possible in only three years at the helm of the club, becoming the all-time record holder of most titles won as a coach at FC Barcelona.

What team did Barcelona's total competition wins pass?
What is the answer?
ANS: Real Madrid
QUES: DST's potential to save energy comes primarily from its effects on residential lighting, which consumes about 3.5% of electricity in the United States and Canada. Delaying the nominal time of sunset and sunrise reduces the use of artificial light in the evening and increases it in the morning. As Franklin's 1784 satire pointed out, lighting costs are reduced if the evening reduction outweighs the morning increase, as in high-latitude summer when most people wake up well after sunrise. An early goal of DST was to reduce evening usage of incandescent lighting, which used to be a primary use of electricity. Although energy conservation remains an important goal, energy usage patterns have greatly changed since then, and recent research is limited and reports contradictory results. Electricity use is greatly affected by geography, climate, and economics, making it hard to generalize from single studies.

When DST was first proposed, what type of lighting was consuming the most electricity?
What is the answer?
ANS: incandescent
QUES: Earthworms are Oligochaetes that support terrestrial food chains both as prey and in some regions are important in aeration and enriching of soil. The burrowing of marine polychaetes, which may constitute up to a third of all species in near-shore environments, encourages the development of ecosystems by enabling water and oxygen to penetrate the sea floor. In addition to improving soil fertility, annelids serve humans as food and as bait. Scientists observe annelids to monitor the quality of marine and fresh water. Although blood-letting is no longer in favor with doctors, some leech species are regarded as endangered species because they have been over-harvested for this purpose in the last few centuries. Ragworms' jaws are now being studied by engineers as they offer an exceptional combination of lightness and strength.

How much of near-shore marine annelids are burrowing?
What is the answer?
ANS:
up to a third
