In 1997, the Bronx was designated an All America City by the National Civic League, acknowledging its comeback from the decline of the mid-century. In 2006, The New York Times reported that "construction cranes have become the borough's new visual metaphor, replacing the window decals of the 1980s in which pictures of potted plants and drawn curtains were placed in the windows of abandoned buildings." The borough has experienced substantial new building construction since 2002. Between 2002 and June 2007, 33,687 new units of housing were built or were under way and $4.8 billion has been invested in new housing. In the first six months of 2007 alone total investment in new residential development was $965 million and 5,187 residential units were scheduled to be completed. Much of the new development is springing up in formerly vacant lots across the South Bronx.
How much was invested in housing in the Bronx in 2002-2007?
****
The answer: $4.8 billion

The alcohol in beer comes primarily from the metabolism of sugars that are produced during fermentation. The quantity of fermentable sugars in the wort and the variety of yeast used to ferment the wort are the primary factors that determine the amount of alcohol in the final beer. Additional fermentable sugars are sometimes added to increase alcohol content, and enzymes are often added to the wort for certain styles of beer (primarily "light" beers) to convert more complex carbohydrates (starches) to fermentable sugars. Alcohol is a by-product of yeast metabolism and is toxic to the yeast; typical brewing yeast cannot survive at alcohol concentrations above 12% by volume. Low temperatures and too little fermentation time decreases the effectiveness of yeasts and consequently decreases the alcohol content.
What could decrease alcohol content during the brewing process?
****
The answer: Low temperatures

Light is the signal by which plants synchronize their internal clocks to their environment and is sensed by a wide variety of photoreceptors. Red and blue light are absorbed through several phytochromes and cryptochromes. One phytochrome, phyA, is the main phytochrome in seedlings grown in the dark but rapidly degrades in light to produce Cry1. Phytochromes BE are more stable with phyB, the main phytochrome in seedlings grown in the light. The cryptochrome (cry) gene is also a light-sensitive component of the circadian clock and is thought to be involved both as a photoreceptor and as part of the clock's endogenous pacemaker mechanism. Cryptochromes 12 (involved in blueUVA) help to maintain the period length in the clock through a whole range of light conditions.
What is the main phytochrome found in seedling grown in light?
****
The answer: phyB

In Prussia, some officials considered a war against France both inevitable and necessary to arouse German nationalism in those states that would allow the unification of a great German empire. This aim was epitomized by Prussian Chancellor Otto von Bismarck's later statement: "I did not doubt that a Franco-German war must take place before the construction of a United Germany could be realised." Bismarck also knew that France should be the aggressor in the conflict to bring the southern German states to side with Prussia, hence giving Germans numerical superiority. Many Germans also viewed the French as the traditional destabilizer of Europe, and sought to weaken France to prevent further breaches of the peace.
In bringing the southern German states to align with Prussia, what tactical outcome was achieved?
****
The answer:
Germans numerical superiority
