From circa 1932 until 1977, General Electric polluted the Housatonic River with PCBs discharges from the General Electric plant at Pittsfield, Massachusetts. Aroclor 1254 and Aroclor 1260, made by Monsanto was the primary contaminant of the pollution. The highest concentrations of PCBs in the Housatonic River are found in Woods Pond in Lenox, Massachusetts, just south of Pittsfield, where they have been measured up to 110 mg/kg in the sediment. About 50% of all the PCBs currently in the river are estimated to be retained in the sediment behind Woods Pond dam. This is estimated to be about 11,000 pounds of PCBs. Former filled oxbows are also polluted. Waterfowl and fish who live in and around the river contain significant levels of PCBs and can present health risks if consumed.
How high have the levels of PCBs in the sediments behind Woods Pond dam been measured at?
****
The answer: 110 mg/kg

In the Netherlands, the Supreme Court of the Netherlands is the highest. Its decisions, known as "arresten", are absolutely final. The court is banned from testing legislation against the constitution, pursuant to the principle of the sovereignty of the States-General; the court can, however, test legislation against some treaties. Also, the ordinary courts in the Netherlands, including the Hoge Raad, do not deal with administrative law, which is dealt with in separate administrative courts, the highest of which is the Council of State (Raad van State)
What areas of interpretative oversight does the supreme court have?
****
The answer: legislation against some treaties

Many early 19th-century neoclassical architects were influenced by the drawings and projects of Étienne-Louis Boullée and Claude Nicolas Ledoux. The many graphite drawings of Boullée and his students depict spare geometrical architecture that emulates the eternality of the universe. There are links between Boullée's ideas and Edmund Burke's conception of the sublime. Ledoux addressed the concept of architectural character, maintaining that a building should immediately communicate its function to the viewer: taken literally such ideas give rise to "architecture parlante".
Who influenced many 19th century neoclassical architects?
****
The answer: Étienne-Louis Boullée and Claude Nicolas Ledoux


The problem: Answer a question about this article:
Two days after "1984" aired, the Macintosh went on sale, and came bundled with two applications designed to show off its interface: MacWrite and MacPaint. It was first demonstrated by Steve Jobs in the first of his famous Mac keynote speeches, and though the Mac garnered an immediate, enthusiastic following, some labeled it a mere "toy." Because the operating system was designed largely around the GUI, existing text-mode and command-driven applications had to be redesigned and the programming code rewritten. This was a time-consuming task that many software developers chose not to undertake, and could be regarded as a reason for an initial lack of software for the new system. In April 1984, Microsoft's MultiPlan migrated over from MS-DOS, with Microsoft Word following in January 1985. In 1985, Lotus Software introduced Lotus Jazz for the Macintosh platform after the success of Lotus 1-2-3 for the IBM PC, although it was largely a flop. Apple introduced the Macintosh Office suite the same year with the "Lemmings" ad. Infamous for insulting its own potential customers, the ad was not successful.
Why did many software developers choose not to redesign the Mac operating system and rewrite the programming code?
****
The answer:
This was a time-consuming task
