QUES: The lower (Triassic) boundary is set by the Permian–Triassic extinction event, during which approximately 90% to 96% of marine species and 70% of terrestrial vertebrates became extinct. It is also known as the "Great Dying" because it is considered the largest mass extinction in the Earth's history. The upper (Cretaceous) boundary is set at the Cretaceous–Tertiary (KT) extinction event (now more accurately called the Cretaceous–Paleogene (or K–Pg) extinction event), which may have been caused by the impactor that created Chicxulub Crater on the Yucatán Peninsula. Towards the Late Cretaceous large volcanic eruptions are also believed to have contributed to the Cretaceous–Paleogene extinction event. Approximately 50% of all genera became extinct, including all of the non-avian dinosaurs.

How many terrestrial species died during the extinction?
What is the answer?
ANS: 70%
QUES: In several countries, fire safety officials encourage citizens to use the two annual clock shifts as reminders to replace batteries in smoke and carbon monoxide detectors, particularly in autumn, just before the heating and candle season causes an increase in home fires. Similar twice-yearly tasks include reviewing and practicing fire escape and family disaster plans, inspecting vehicle lights, checking storage areas for hazardous materials, reprogramming thermostats, and seasonal vaccinations. Locations without DST can instead use the first days of spring and autumn as reminders.

If your area doesn't observe DST, what can you use instead as a twice-yearly reminder?
What is the answer?
ANS: the first days of spring and autumn
QUES: Anarchists are against the State but are not against political organization or "governance"—so long as it is self-governance utilizing direct democracy. The mode of political organization preferred by anarchists, in general, is federalism or confederalism.[citation needed] However, the anarchist definition of federalism tends to differ from the definition of federalism assumed by pro-state political scientists. The following is a brief description of federalism from section I.5 of An Anarchist FAQ:
