Article: The Arsacid Kingdom of Armenia, itself a branch of the Arsacid dynasty of Parthia, was the first state to adopt Christianity as its religion (it had formerly been adherent to Armenian paganism, which was influenced by Zoroastrianism, while later on adopting a few elements regarding identification of its pantheon with Greco-Roman deities). in the early years of the 4th century, likely AD 301, partly in defiance of the Sassanids it seems. In the late Parthian period, Armenia was a predominantly Zoroastrian-adhering land, but by the Christianisation, previously predominant Zoroastrianism and paganism in Armenia gradually declined. Later on, in order to further strengthen Armenian national identity, Mesrop Mashtots invented the Armenian alphabet, in 405 AD. This event ushered the Golden Age of Armenia, during which many foreign books and manuscripts were translated to Armenian by Mesrop's pupils. Armenia lost its sovereignty again in 428 AD to the rivalling Byzantine and Sassanid Persian empires, until the Muslim conquest of Persia overran also the regions in which Armenians lived.

Question: Who invented the Armenian alphabet?
Ans: Mesrop Mashtots


Here is a question about this article: Discrete transistors are individually packaged transistors. Transistors come in many different semiconductor packages (see image). The two main categories are through-hole (or leaded), and surface-mount, also known as surface-mount device (SMD). The ball grid array (BGA) is the latest surface-mount package (currently only for large integrated circuits). It has solder "balls" on the underside in place of leads. Because they are smaller and have shorter interconnections, SMDs have better high-frequency characteristics but lower power rating.
What is the answer to this question: What is another name for the surface-mount transistor?
****
So... surface-mount device (SMD)

The New York Marathon is one of the world's largest, and the 2004–2006 events hold the top three places in the marathons with the largest number of finishers, including 37,866 finishers in 2006. The Millrose Games is an annual track and field meet whose featured event is the Wanamaker Mile. Boxing is also a prominent part of the city's sporting scene, with events like the Amateur Boxing Golden Gloves being held at Madison Square Garden each year. The city is also considered the host of the Belmont Stakes, the last, longest and oldest of horse racing's Triple Crown races, held just over the city's border at Belmont Park on the first or second Sunday of June. The city also hosted the 1932 U.S. Open golf tournament and the 1930 and 1939 PGA Championships, and has been host city for both events several times, most notably for nearby Winged Foot Golf Club.
Which years did NYC host the PGA golf championships?
A: 1930 and 1939


Question: Read this and answer the question

Iran's climate ranges from arid or semiarid, to subtropical along the Caspian coast and the northern forests. On the northern edge of the country (the Caspian coastal plain) temperatures rarely fall below freezing and the area remains humid for the rest of the year. Summer temperatures rarely exceed 29 °C (84.2 °F). Annual precipitation is 680 mm (26.8 in) in the eastern part of the plain and more than 1,700 mm (66.9 in) in the western part. United Nations Resident Coordinator for Iran Gary Lewis has said that "Water scarcity poses the most severe human security challenge in Iran today".

What is the annual precipitation in Iran's western plains?
Answer:
1,700 mm (66.9 in)
