Problem: "Old Style" (OS) and "New Style" (NS) are sometimes added to dates to identify which system is used in the British Empire and other countries that did not immediately change. Because the Calendar Act of 1750 altered the start of the year, and also aligned the British calendar with the Gregorian calendar, there is some confusion as to what these terms mean. They can indicate that the start of the Julian year has been adjusted to start on 1 January (NS) even though contemporary documents use a different start of year (OS); or to indicate that a date conforms to the Julian calendar (OS), formerly in use in many countries, rather than the Gregorian calendar (NS).
With what did the Calendar Act align the British calendar?

Answer: Gregorian calendar

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
During the summer months, it is common for temperatures to reach over 90 F (32 C), with an average of 106.5 days per year, including a majority from June to September, with a high of 90 F or above and 4.6 days at or over 100 F (38 C). However, humidity usually yields a higher heat index. Summer mornings average over 90 percent relative humidity. Winds are often light in the summer and offer little relief, except in the far southeastern outskirts near the Gulf coast and Galveston. To cope with the strong humidity and heat, people use air conditioning in nearly every vehicle and building. In 1980, Houston was described as the "most air-conditioned place on earth". Officially, the hottest temperature ever recorded in Houston is 109 F (43 C), which was reached both on September 4, 2000 and August 28, 2011.
What was the highest temperature recorded in Houston?
A: 109 F

The growing popularity of such artists led to the emergence of electro house and progressive house blended sounds in popular music, such as singles Lady Gaga's "Marry the Night", The Black Eyed Peas' "The Best One Yet (The Boy)" and the will.i.am and Britney Spears "Scream & Shout". Big room house found increasing popularity since 2010, particularly through international dance music festivals such as Tomorrowland, Ultra Music Festival, and Electric Daisy Carnival.

Immigration to Israel during the late 1940s and early 1950s was aided by the Israeli Immigration Department and the non-government sponsored Mossad LeAliyah Bet ("Institution for Illegal Immigration"). Both groups facilitated regular immigration logistics like arranging transportation, but the latter also engaged in clandestine operations in countries, particularly in the Middle East and Eastern Europe, where the lives of Jews were believed to be in danger and exit from those places was difficult. Mossad LeAliyah Bet continued to take part in immigration efforts until its disbanding in 1953. An influx of Holocaust survivors and Jews from Arab and Muslim lands immigrated to Israel during the first 3 years and the number of Jews increased from 700,000 to 1,400,000, many of whom faced persecution in their original countries. The immigration was in accordance with the One Million Plan.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): The immigration was in accordance to what?
Ah, so..
One Million Plan
