Problem: Some insects display a rudimentary sense of numbers, such as the solitary wasps that prey upon a single species. The mother wasp lays her eggs in individual cells and provides each egg with a number of live caterpillars on which the young feed when hatched. Some species of wasp always provide five, others twelve, and others as high as twenty-four caterpillars per cell. The number of caterpillars is different among species, but always the same for each sex of larva. The male solitary wasp in the genus Eumenes is smaller than the female, so the mother of one species supplies him with only five caterpillars; the larger female receives ten caterpillars in her cell.
Which insect displays a rudimentary sense of numbers?
The answer is the following: solitary wasps

Problem: India rejected Chinese demands that the torch route be clear of India's 150,000-strong Tibetan exile community, by which they required a ban on congregation near the curtailed 3 km route. In response Indian officials said India was a democracy, and "a wholesale ban on protests was out of the question". Contradicting some other reports, Indian officials also refused permission to the "Olympic Holy Flame Protection Unit". The combined effect is a "rapid deterioration" of relations between India and China. Meanwhile, the Tibetan government in exile, which is based in India, has stated that it did not support the disruption of the Olympic torch relay.
Who said they did not support relay interruptions?
The answer is the following: the Tibetan government in exile

Problem: Aside from water, wood has three main components. Cellulose, a crystalline polymer derived from glucose, constitutes about 4143%. Next in abundance is hemicellulose, which is around 20% in deciduous trees but near 30% in conifers. It is mainly five-carbon sugars that are linked in an irregular manner, in contrast to the cellulose. Lignin is the third component at around 27% in coniferous wood vs. 23% in deciduous trees. Lignin confers the hydrophobic properties reflecting the fact that it is based on aromatic rings. These three components are interwoven, and direct covalent linkages exist between the lignin and the hemicellulose. A major focus of the paper industry is the separation of the lignin from the cellulose, from which paper is made.
How many main components make up wood, not counting water?
The answer is the following: three

Problem: Philadelphia has dedicated landmarks to its sister cities. Dedicated in June 1976, the Sister Cities Plaza, a site of 0.5 acres (2,000 m2) located at 18th and Benjamin Franklin Parkway, honors Philadelphia's relationships with Tel Aviv and Florence which were its first sister cities. Another landmark, the Torun Triangle, honoring the sister city relationship with Torun, Poland, was constructed in 1976, west of the United Way building at 18th Street and the Benjamin Franklin Parkway. In addition, the Triangle contains the Copernicus monument. Renovations were made to Sister Cities Park in mid-2011 and on May 10, 2012, SCP was reopened and currently features an interactive fountain honoring Philadelphia's ten sister and friendship cities, a cafe and visitor's center, children's play area, outdoor garden, and boat pond, as well as pavilion built to environmentally friendly standards.
How many sister cities does Philadelphia have?
The answer is the following:
ten
