Problem: The modern English word green comes from the Middle English and Anglo-Saxon word grene, from the same Germanic root as the words "grass" and "grow". It is the color of living grass and leaves and as a result is the color most associated with springtime, growth and nature. By far the largest contributor to green in nature is chlorophyll, the chemical by which plants photosynthesize and convert sunlight into chemical energy. Many creatures have adapted to their green environments by taking on a green hue themselves as camouflage. Several minerals have a green color, including the emerald, which is colored green by its chromium content.
For what do some animals use the color green?
The answer is the following: camouflage

Problem: Like in English, Dutch has generalised the dative over the accusative case for all pronouns, e.g. Du me, je, Eng me, you, vs. Germ mich/mir dich/dir. There is one exception: the standard language prescribes that in the third person plural, hen is to be used for the direct object, and hun for the indirect object. This distinction was artificially introduced in the 17th century by grammarians, and is largely ignored in spoken language and not well understood by Dutch speakers. Consequently, the third person plural forms hun and hen are interchangeable in normal usage, with hun being more common. The shared unstressed form ze is also often used as both direct and indirect objects and is a useful avoidance strategy when people are unsure which form to use.
When did the grammarians first draw the line between third person plural pronouns for Dutch?
The answer is the following: 17th century

Problem: The record attendance for an Everton home match is 78,299 against Liverpool on 18 September 1948. Amazingly, there was only 1 injury at this game-Tom Fleetwood was hit on the head by a coin thrown from the crowd whilst he marched around the perimeter with St Edward's Orphanage Band, playing the cornet. Goodison Park, like all major English football grounds since the recommendations of the Taylor Report were implemented, is now an all-seater and only holds just under 40,000, meaning it is unlikely that this attendance record will ever be broken at Goodison. Everton's record transfer paid was to Chelsea for Belgian forward Romelu Lukaku for a sum of £28m. Everton bought the player after he played the previous year with the team on loan.
How many fans were injured in Everton's 1948 match against Liverpool that drew the largest crowd they've had?
The answer is the following: 1

Problem: Spirometry is recommended to aid in diagnosis and management. It is the single best test for asthma. If the FEV1 measured by this technique improves more than 12% following administration of a bronchodilator such as salbutamol, this is supportive of the diagnosis. It however may be normal in those with a history of mild asthma, not currently acting up. As caffeine is a bronchodilator in people with asthma, the use of caffeine before a lung function test may interfere with the results. Single-breath diffusing capacity can help differentiate asthma from COPD. It is reasonable to perform spirometry every one or two years to follow how well a person's asthma is controlled.
What helps support the evidence of asthma?
The answer is the following:
If the FEV1 measured by this technique improves more than 12% following administration of a bronchodilator
