The climate of the Cretaceous is less certain and more widely disputed. Higher levels of carbon dioxide in the atmosphere are thought to have caused the world temperature gradient from north to south to become almost flat: temperatures were about the same across the planet. Average temperatures were also higher than today by about 10°C. In fact, by the middle Cretaceous, equatorial ocean waters (perhaps as warm as 20 °C in the deep ocean) may have been too warm for sea life,[dubious – discuss][citation needed] and land areas near the equator may have been deserts despite their proximity to water. The circulation of oxygen to the deep ocean may also have been disrupted.[dubious – discuss] For this reason, large volumes of organic matter that was unable to decompose accumulated, eventually being deposited as "black shale".
What did large amounts of deposited un-decomposed organic matter later become?
A: black shale

The Battle of Wörth (also known as Fröschwiller or Reichshoffen) began when the two armies clashed again on 6 August near Wörth in the town of Fröschwiller, about 10 miles (16 km) from Wissembourg. The Crown Prince of Prussia's 3rd army had, on the quick reaction of his Chief of Staff General von Blumenthal, drawn reinforcements which brought its strength up to 140,000 troops. The French had been slowly reinforced and their force numbered only 35,000. Although badly outnumbered, the French defended their position just outside Fröschwiller. By afternoon, the Germans had suffered c. 10,500 killed or wounded and the French had lost a similar number of casualties and another c. 9,200 men taken prisoner, a loss of about 50%. The Germans captured Fröschwiller which sat on a hilltop in the centre of the French line. Having lost any hope for victory and facing a massacre, the French army disengaged and retreated in a westerly direction towards Bitche and Saverne, hoping to join French forces on the other side of the Vosges mountains. The German 3rd army did not pursue the French but remained in Alsace and moved slowly south, attacking and destroying the French garrisons in the vicinity.
What number of troops did France have to contend with?
A: 35,000

Bush focused his campaign on national security, presenting himself as a decisive leader and contrasted Kerry as a "flip-flopper." This strategy was designed to convey to American voters the idea that Bush could be trusted to be tough on terrorism while Kerry would be "uncertain in the face of danger." Bush (just as his father did with Dukakis in the 1988 election) also sought to portray Kerry as a "Massachusetts liberal" who was out of touch with mainstream Americans. One of Kerry's slogans was "Stronger at home, respected in the world." This advanced the suggestion that Kerry would pay more attention to domestic concerns; it also encapsulated Kerry's contention that Bush had alienated American allies by his foreign policy.
What attitude did Dukakis have on terrorism?
A:
unanswerable
