The global dog population is estimated at 525 million:225 based on a transparent methodology, as opposed to other estimates where the methodology has not been made available – all dog population estimates are based on regional human population densities and land uses.
What are dog population estimates based on other than land uses?
human population densities


Input: Race (human categorization)
One crucial innovation in reconceptualizing genotypic and phenotypic variation was the anthropologist C. Loring Brace's observation that such variations, insofar as it is affected by natural selection, slow migration, or genetic drift, are distributed along geographic gradations or clines. In part this is due to isolation by distance. This point called attention to a problem common to phenotype-based descriptions of races (for example, those based on hair texture and skin color): they ignore a host of other similarities and differences (for example, blood type) that do not correlate highly with the markers for race. Thus, anthropologist Frank Livingstone's conclusion, that since clines cross racial boundaries, "there are no races, only clines".

What is a problem common to phenotype-based descriptions of races?
Output: they ignore a host of other similarities and differences


Input: Article: Neutering refers to the sterilization of animals, usually by removal of the male's testicles or the female's ovaries and uterus, in order to eliminate the ability to procreate and reduce sex drive. Because of the overpopulation of dogs in some countries, many animal control agencies, such as the American Society for the Prevention of Cruelty to Animals (ASPCA), advise that dogs not intended for further breeding should be neutered, so that they do not have undesired puppies that may have to later be euthanized.

Now answer this question: In neutering, what is removed in female dogs?

Output: ovaries and uterus


Article: For at least a century before the establishment of the Augustan principate, Jews and Judaism were tolerated in Rome by diplomatic treaty with Judaea's Hellenised elite. Diaspora Jews had much in common with the overwhelmingly Hellenic or Hellenised communities that surrounded them. Early Italian synagogues have left few traces; but one was dedicated in Ostia around the mid-1st century BC and several more are attested during the Imperial period. Judaea's enrollment as a client kingdom in 63 BC increased the Jewish diaspora; in Rome, this led to closer official scrutiny of their religion. Their synagogues were recognised as legitimate collegia by Julius Caesar. By the Augustan era, the city of Rome was home to several thousand Jews. In some periods under Roman rule, Jews were legally exempt from official sacrifice, under certain conditions. Judaism was a superstitio to Cicero, but the Church Father Tertullian described it as religio licita (an officially permitted religion) in contrast to Christianity.

Question: When did Judea become an allied kingdom to Rome?
Ans: 63 BC


Here is a question about this article: While the French army under General MacMahon engaged the German 3rd Army at the Battle of Wörth, the German 1st Army under Steinmetz finished their advance west from Saarbrücken. A patrol from the German 2nd Army under Prince Friedrich Karl of Prussia spotted decoy fires close and Frossard's army farther off on a distant plateau south of the town of Spicheren, and took this as a sign of Frossard's retreat. Ignoring Moltke's plan again, both German armies attacked Frossard's French 2nd Corps, fortified between Spicheren and Forbach.
What is the answer to this question: What did a German patrol spot that led them to believe that Frossard had retreated?
****
So... decoy fires


Article: Voyager 2 is the only spacecraft that has visited Neptune. The spacecraft's closest approach to the planet occurred on 25 August 1989. Because this was the last major planet the spacecraft could visit, it was decided to make a close flyby of the moon Triton, regardless of the consequences to the trajectory, similarly to what was done for Voyager 1's encounter with Saturn and its moon Titan. The images relayed back to Earth from Voyager 2 became the basis of a 1989 PBS all-night program, Neptune All Night.

Question: What program aired on PBS about Neptune?
Ans:
Neptune All Night
