Problem: The fauna in the state is just as diverse as the flora and varies greatly due to the large contrast in climates. In the mountain zone of the state the most observed mammals are: Mexican fox squirrel (Sciurus nayaritensis), antelope jackrabbit (Lepus alleni), raccoon (Procyon lotor), hooded skunk (Mephitis macroura), wild boar (Sus scrofa), collared peccary (Pecari tajacu), white-tailed deer (Odocoileus virginianus), mule deer Odocoileus hemionus, American bison Bison bison, cougar (Puma concolor), eastern cottontail Sylvilagus floridanus, North American porcupine Erethizon dorsatum, bobcat Lynx rufus, Mexican wolf Canis lupus baileyi, and coyote Canis latrans. American black bear Ursus americanus is also found but in very small numbers. The Mexican wolf, once abundant, has been extirpated. The main cause of degradation has been grazing. Although there are many reptilian species in the mountains the most observed species include: Northern Mexican pine snake, Pituophis deppei jani, Texas horned lizard (Phrynosoma cornutum), rock rattlesnake (Crotalus lepidus), black-tailed rattlesnake (Crotalus molossus), and plateau tiger salamander Ambystoma velasci, one of possibly many amphibians to be found in the mountains.
What type of snake is most popular in the region with many different species?
The answer is the following: rattlesnake

Problem: Prior to the 20th century drugs were generally produced by small scale manufacturers with little regulatory control over manufacturing or claims of safety and efficacy. To the extent that such laws did exist, enforcement was lax. In the United States, increased regulation of vaccines and other biological drugs was spurred by tetanus outbreaks and deaths caused by the distribution of contaminated smallpox vaccine and diphtheria antitoxin. The Biologics Control Act of 1902 required that federal government grant premarket approval for every biological drug and for the process and facility producing such drugs. This was followed in 1906 by the Pure Food and Drugs Act, which forbade the interstate distribution of adulterated or misbranded foods and drugs. A drug was considered misbranded if it contained alcohol, morphine, opium, cocaine, or any of several other potentially dangerous or addictive drugs, and if its label failed to indicate the quantity or proportion of such drugs. The government's attempts to use the law to prosecute manufacturers for making unsupported claims of efficacy were undercut by a Supreme Court ruling restricting the federal government's enforcement powers to cases of incorrect specification of the drug's ingredients.
Who restricted the federal government's enforcement powers?
The answer is the following: Supreme Court

Problem: Antonio Vivaldi composed a mandolin concerto (Concerto in C major Op.3 6) and two concertos for two mandolins and orchestra. Wolfgang Amadeus Mozart placed it in his 1787 work Don Giovanni and Beethoven created four variations of it. Antonio Maria Bononcini composed La conquista delle Spagne di Scipione Africano il giovane in 1707 and George Frideric Handel composed Alexander Balus in 1748. Others include Giovani Battista Gervasio (Sonata in D major for Mandolin and Basso Continuo), Giuseppe Giuliano (Sonata in D major for Mandolin and Basso Continuo), Emanuele Barbella (Sonata in D major for Mandolin and Basso Continuo), Domenico Scarlatti (Sonata n.54 (K.89) in D minor for Mandolin and Basso Continuo), and Addiego Guerra (Sonata in G major for Mandolin and Basso Continuo).
What two artists created four variations of the Concerto in C Major Op 3 6?
The answer is the following: Don Giovanni and Beethoven

Problem: Larger SAMs may be deployed in fixed launchers, but can be towed/re-deployed at will. The SAMs launched by individuals are known in the United States as the Man-Portable Air Defence Systems (MANPADS). MANPADS of the former Soviet Union have been exported around the World, and can be found in use by many armed forces. Targets for non-ManPAD SAMs will usually be acquired by air-search radar, then tracked before/while a SAM is "locked-on" and then fired. Potential targets, if they are military aircraft, will be identified as friend or foe before being engaged. The developments in the latest and relatively cheap short-range missiles have begun to replace autocannons in this role.
What does MANPADS mean?
The answer is the following:
Man-Portable Air Defence Systems
