Insects are the only invertebrates to have developed active flight capability, and this has played an important role in their success.:186 Their muscles are able to contract multiple times for each single nerve impulse, allowing the wings to beat faster than would ordinarily be possible. Having their muscles attached to their exoskeletons is more efficient and allows more muscle connections; crustaceans also use the same method, though all spiders use hydraulic pressure to extend their legs, a system inherited from their pre-arthropod ancestors. Unlike insects, though, most aquatic crustaceans are biomineralized with calcium carbonate extracted from the water.
Insects are also known as what kind of vertebra?
invertebrates

Input: United States presidential election, 2004
In March's Super Tuesday, Kerry won decisive victories in the California, Connecticut, Georgia, Maryland, Massachusetts, New York, Ohio, and Rhode Island primaries and the Minnesota caucuses. Dean, despite having withdrawn from the race two weeks earlier, won his home state of Vermont. Edwards finished only slightly behind Kerry in Georgia, but, failing to win a single state other than South Carolina, chose to withdraw from the presidential race. Sharpton followed suit a couple weeks later. Kuninch did not leave the race officially until July.

Besides Georgia, what other state primary did Edwards win?
Output: South Carolina

Input: Article: The Egyptians begrudgingly accepted the Ptolemies as the successors to the pharaohs of independent Egypt, though the kingdom went through several native revolts. The Ptolemies took on the traditions of the Egyptian Pharaohs, such as marrying their siblings (Ptolemy II was the first to adopt this custom), having themselves portrayed on public monuments in Egyptian style and dress, and participating in Egyptian religious life. The Ptolemaic ruler cult portrayed the Ptolemies as gods, and temples to the Ptolemies were erected throughout the kingdom. Ptolemy I even created a new god, Serapis, who was combination of two Egyptian gods: Apis and Osiris, with attributes of Greek gods. Ptolemaic administration was, like the Ancient Egyptian bureaucracy, highly centralized and focused on squeezing as much revenue out of the population as possible though tariffs, excise duties, fines, taxes and so forth. A whole class of petty officials, tax farmers, clerks and overseers made this possible. The Egyptian countryside was directly administered by this royal bureaucracy. External possessions such as Cyprus and Cyrene were run by strategoi, military commanders appointed by the crown.

Now answer this question: Whose tradition did Ptolemy take on as leader of Egypt?

Output: Egyptian Pharaohs

Article: Large brushes are desired for a larger brush contact area to maximize motor output, but small brushes are desired for low mass to maximize the speed at which the motor can run without the brushes excessively bouncing and sparking. (Small brushes are also desirable for lower cost.) Stiffer brush springs can also be used to make brushes of a given mass work at a higher speed, but at the cost of greater friction losses (lower efficiency) and accelerated brush and commutator wear. Therefore, DC motor brush design entails a trade-off between output power, speed, and efficiency/wear.

Question: Besides wear, what is a downside of stiff brush springs?
Ans: lower efficiency

Here is a question about this article: In the early 19th century, Augustus Welby Northmore Pugin wrote Contrasts (1836) that, as the titled suggested, contrasted the modern, industrial world, which he disparaged, with an idealized image of neo-medieval world. Gothic architecture, Pugin believed, was the only "true Christian form of architecture."
What is the answer to this question: Who wrote the book Contrasts?
****
So... Augustus Welby Northmore Pugin

Article: In the Miocene Epoch the mountains underwent severe erosion because of glaciation, which was noted in the mid-19th century by naturalist Louis Agassiz who presented a paper proclaiming the Alps were covered in ice at various intervalsa theory he formed when studying rocks near his Neuchatel home which he believed originated to the west in the Bernese Oberland. Because of his work he came to be known as the "father of the ice-age concept" although other naturalists before him put forth similar ideas.

Question: What was the cause of the severe erosion?
Ans:
glaciation
