Input: Dog
The dogs' value to early human hunter-gatherers led to them quickly becoming ubiquitous across world cultures. Dogs perform many roles for people, such as hunting, herding, pulling loads, protection, assisting police and military, companionship, and, more recently, aiding handicapped individuals. This impact on human society has given them the nickname "man's best friend" in the Western world. In some cultures, however, dogs are also a source of meat.

Dogs have hunted with and done other things for people for a long time, but what is a more recent help to people they provide?
Output: aiding handicapped individuals.

Input: Article: Saint Helena has the international calling code +290 which, since 2006, Tristan da Cunha shares. Saint Helena telephone numbers changed from 4 to 5 digits on 1 October 2013 by being prefixed with the digit "2", i.e. 2xxxx, with the range 5xxxx being reserved for mobile numbering, and 8xxx being used for Tristan da Cunha numbers (these still shown as 4 digits).

Now answer this question: When did Saint Helena change the amount of digits in their phone numbers?

Output: 1 October 2013

Article: Emotions can motivate social interactions and relationships and therefore are directly related with basic physiology, particularly with the stress systems. This is important because emotions are related to the anti-stress complex, with an oxytocin-attachment system, which plays a major role in bonding. Emotional phenotype temperaments affect social connectedness and fitness in complex social systems (Kurt Kortschal 2013). These characteristics are shared with other species and taxa and are due to the effects of genes and their continuous transmission. Information that is encoded in the DNA sequences provides the blueprint for assembling proteins that make up our cells. Zygotes require genetic information from their parental germ cells, and at every speciation event, heritable traits that have enabled its ancestor to survive and reproduce successfully are passed down along with new traits that could be potentially beneficial to the offspring. In the five million years since the linages leading to modern humans and chimpanzees split, only about 1.2% of their genetic material has been modified. This suggests that everything that separates us from chimpanzees must be encoded in that very small amount of DNA, including our behaviors. Students that study animal behaviors have only identified intraspecific examples of gene-dependent behavioral phenotypes. In voles (Microtus spp.) minor genetic differences have been identified in a vasopressin receptor gene that corresponds to major species differences in social organization and the mating system (Hammock & Young 2005). Another potential example with behavioral differences is the FOCP2 gene, which is involved in neural circuitry handling speech and language (Vargha-Khadem et al. 2005). Its present form in humans differed from that of the chimpanzees by only a few mutations and has been present for about 200,000 years, coinciding with the beginning of modern humans (Enard et al. 2002). Speech, language, and social organization are all part of the basis for emotions.

Question: How many million years ago did the evolution of chimpanzees and humans diverge?
Ans: five

Here is a question about this article: Large quantities of H
2 are needed in the petroleum and chemical industries. The largest application of H
2 is for the processing ("upgrading") of fossil fuels, and in the production of ammonia. The key consumers of H
2 in the petrochemical plant include hydrodealkylation, hydrodesulfurization, and hydrocracking. H
2 has several other important uses. H
2 is used as a hydrogenating agent, particularly in increasing the level of saturation of unsaturated fats and oils (found in items such as margarine), and in the production of methanol. It is similarly the source of hydrogen in the manufacture of hydrochloric acid. H
2 is also used as a reducing agent of metallic ores.
What is the answer to this question: Where are large quantities of H2 needed?
****
So... petroleum and chemical industries

W 122nd Street runs six blocks (3,280 feet (1,000 m)) west from the intersection of Mount Morris Park West at Marcus Garvey Memorial Park and terminates at the intersection of Morningside Avenue at Morningside Park. This segment runs in the Mount Morris Historical District and crosses portions of Lenox Avenue (Sixth Avenue), Seventh Avenue, Frederick Douglass Boulevard (Eighth Avenue), and Manhattan Avenue.
At which park does W 122nd Street end?
****
The answer: Morningside Park

The problem: Answer a question about this article:
CNET awarded PS3 Slim four out of five stars praising its Blu-ray capabilities, 120 GB hard drive, free online gaming service and more affordable pricing point, but complained about the lack of backward compatibility for PlayStation 2 games. TechRadar gave PS3 Slim four and a half stars out of five praising its new smaller size and summed up its review stating "Over all, the PS3 Slim is a phenomenal piece of kit. It's amazing that something so small can do so much". However, they criticized the exterior design and the build quality in relation to the original model.
What area of the console did TechRadar feel was designed poorly compared to the original PS3?
****
The answer:
exterior
