Input: Read this: Motorcycles are also commonly used, particularly in locations that a car may not be able to reach, to control potential public order situations involving meetings of motorcyclists and often in escort duties where motorcycle police officers can quickly clear a path for escorted vehicles. Bicycle patrols are used in some areas because they allow for more open interaction with the public. In addition, their quieter operation can facilitate approaching suspects unawares and can help in pursuing them attempting to escape on foot.
Question: What don't police use to control motorcyclist events?

Output: unanswerable


QUES: Strasbourg also offers high-class eclecticist buildings in its very extended German district, the Neustadt, being the main memory of Wilhelmian architecture since most of the major cities in Germany proper suffered intensive damage during World War II. Streets, boulevards and avenues are homogeneous, surprisingly high (up to seven stories) and broad examples of German urban lay-out and of this architectural style that summons and mixes up five centuries of European architecture as well as Neo-Egyptian, Neo-Greek and Neo-Babylonian styles. The former imperial palace Palais du Rhin, the most political and thus heavily criticized of all German Strasbourg buildings epitomizes the grand scale and stylistic sturdiness of this period. But the two most handsome and ornate buildings of these times are the École internationale des Pontonniers (the former Höhere Mädchenschule, girls college) with its towers, turrets and multiple round and square angles and the École des Arts décoratifs with its lavishly ornate façade of painted bricks, woodwork and majolica.

How high were some of the buildings in urban Germany?
What is the answer?
ANS: seven stories


QUES: The epidermis is typically 10 to 30 cells thick; its main function is to provide a waterproof layer. Its outermost cells are constantly lost; its bottommost cells are constantly dividing and pushing upward. The middle layer, the dermis, is 15 to 40 times thicker than the epidermis. The dermis is made up of many components, such as bony structures and blood vessels. The hypodermis is made up of adipose tissue. Its job is to store lipids, and to provide cushioning and insulation. The thickness of this layer varies widely from species to species.
How much more thicker is the dermis to the epidermis?

ANS: 15 to 40 times thicker


In All Life is Problem Solving, Popper sought to explain the apparent progress of scientific knowledge – that is, how it is that our understanding of the universe seems to improve over time. This problem arises from his position that the truth content of our theories, even the best of them, cannot be verified by scientific testing, but can only be falsified. Again, in this context the word "falsified" does not refer to something being "fake"; rather, that something can be (i.e., is capable of being) shown to be false by observation or experiment. Some things simply do not lend themselves to being shown to be false, and therefore, are not falsifiable. If so, then how is it that the growth of science appears to result in a growth in knowledge? In Popper's view, the advance of scientific knowledge is an evolutionary process characterised by his formula:
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What part of theories can be verified by scientific testing?
Ah, so.. unanswerable


Question: Fossilized spores suggest that higher plants (embryophytes) have lived on land for at least 475 million years. Early land plants reproduced sexually with flagellated, swimming sperm, like the green algae from which they evolved. An adaptation to terrestrialization was the development of upright meiosporangia for dispersal by spores to new habitats. This feature is lacking in the descendants of their nearest algal relatives, the Charophycean green algae. A later terrestrial adaptation took place with retention of the delicate, avascular sexual stage, the gametophyte, within the tissues of the vascular sporophyte. This occurred by spore germination within sporangia rather than spore release, as in non-seed plants. A current example of how this might have happened can be seen in the precocious spore germination in Selaginella, the spike-moss. The result for the ancestors of angiosperms was enclosing them in a case, the seed. The first seed bearing plants, like the ginkgo, and conifers (such as pines and firs), did not produce flowers. The pollen grains (males) of Ginkgo and cycads produce a pair of flagellated, mobile sperm cells that "swim" down the developing pollen tube to the female and her eggs.
Try to answer this question if possible: What are the nearest algal relatives existing today?
Answer: Charophycean green algae


Input: Read this: The hypnotic electronic dance song "On and On", produced in 1984 by Chicago DJ Jesse Saunders and co-written by Vince Lawrence, had elements that became staples of the early house sound, such as the Roland TB-303 bass synthesizer and minimal vocals as well as a Roland (specifically TR-808) drum machine and Korg (specifically Poly-61) synthesizer. It also utilized the bassline from Player One's disco record "Space Invaders" (1979). "On and On" is sometimes cited as the 'first house record', though other examples from around that time, such as J.M. Silk's "Music is the Key" (1985), have also been cited.
Question: what type of bass synthesizer was a staple of the early house sound?

Output:
Roland TB-303
