Question: In 1996 Brewster Kahle, with Bruce Gilliat, developed software to crawl and download all publicly accessible World Wide Web pages, the Gopher hierarchy, the Netnews (Usenet) bulletin board system, and downloadable software. The information collected by these "crawlers" does not include all the information available on the Internet, since much of the data is restricted by the publisher or stored in databases that are not accessible. These "crawlers" also respect the robots exclusion standard for websites whose owners opt for them not to appear in search results or be cached. To overcome inconsistencies in partially cached web sites, Archive-It.org was developed in 2005 by the Internet Archive as a means of allowing institutions and content creators to voluntarily harvest and preserve collections of digital content, and create digital archives.
Is there an answer to this question: What rule do web sites abide by when determining sites to record?

Answer: unanswerable


Question: During the process of meiotic cell division, an event called genetic recombination or crossing-over can sometimes occur, in which a length of DNA on one chromatid is swapped with a length of DNA on the corresponding sister chromatid. This has no effect if the alleles on the chromatids are the same, but results in reassortment of otherwise linked alleles if they are different.:5.5 The Mendelian principle of independent assortment asserts that each of a parent's two genes for each trait will sort independently into gametes; which allele an organism inherits for one trait is unrelated to which allele it inherits for another trait. This is in fact only true for genes that do not reside on the same chromosome, or are located very far from one another on the same chromosome. The closer two genes lie on the same chromosome, the more closely they will be associated in gametes and the more often they will appear together; genes that are very close are essentially never separated because it is extremely unlikely that a crossover point will occur between them. This is known as genetic linkage.
Is there an answer to this question: If the alleles on the chromatids are the same, what effect arises from genetic recombination? 

Answer: no effect


Question: The League of American Bicyclists gave Tucson a gold rating for bicycle friendliness in late April 2007. Tucson hosts the largest perimeter cycling event in the United States. The ride called "El Tour de Tucson" happens in November on the Saturday before Thanksgiving. El Tour de Tucson produced and promoted by Perimeter Bicycling has as many as 10,000 participants from all over the world, annually. Tucson is one of only nine cities in the U.S. to receive a gold rating or higher for cycling friendliness from the League of American Bicyclists. The city is known for its winter cycling opportunities. Both road and mountain biking are popular in and around Tucson with trail areas including Starr Pass and Fantasy Island.
Is there an answer to this question: Who runs El Tour de Tucson?

Answer: Perimeter Bicycling


Question: The positions on the persistence of objects are somewhat similar. An endurantist holds that for an object to persist through time is for it to exist completely at different times (each instance of existence we can regard as somehow separate from previous and future instances, though still numerically identical with them). A perdurantist on the other hand holds that for a thing to exist through time is for it to exist as a continuous reality, and that when we consider the thing as a whole we must consider an aggregate of all its "temporal parts" or instances of existing. Endurantism is seen as the conventional view and flows out of our pre-philosophical ideas (when I talk to somebody I think I am talking to that person as a complete object, and not just a part of a cross-temporal being), but perdurantists have attacked this position. (An example of a perdurantist is David Lewis.) One argument perdurantists use to state the superiority of their view is that perdurantism is able to take account of change in objects.
Is there an answer to this question: What does endurantism take account of the change in?

Answer:
unanswerable
