Input: Read this: After a lengthy period of formal racial segregation in the former Confederacy following the Reconstruction Era, and bans on interracial marriage in various parts of the country, more people are openly forming interracial unions. In addition, social conditions have changed and many multiracial people do not believe it is socially advantageous to try to "pass" as white. Diverse immigration has brought more mixed-race people into the United States, such as the large population of Hispanics identifying as mestizos. Since the 1980s, the United States has had a growing multiracial identity movement (cf. Loving Day). Because more Americans have insisted on being allowed to acknowledge their mixed racial origins, the 2000 census for the first time allowed residents to check more than one ethno-racial identity and thereby identify as multiracial. In 2008 Barack Obama was elected as the first multiracial President of the United States; he acknowledges both sides of his family and identifies as African American.
Question: What are less people openly doing than in the past?

Output: unanswerable


QUES: Solar concentrating technologies such as parabolic dish, trough and Scheffler reflectors can provide process heat for commercial and industrial applications. The first commercial system was the Solar Total Energy Project (STEP) in Shenandoah, Georgia, USA where a field of 114 parabolic dishes provided 50% of the process heating, air conditioning and electrical requirements for a clothing factory. This grid-connected cogeneration system provided 400 kW of electricity plus thermal energy in the form of 401 kW steam and 468 kW chilled water, and had a one-hour peak load thermal storage. Evaporation ponds are shallow pools that concentrate dissolved solids through evaporation. The use of evaporation ponds to obtain salt from sea water is one of the oldest applications of solar energy. Modern uses include concentrating brine solutions used in leach mining and removing dissolved solids from waste streams. Clothes lines, clotheshorses, and clothes racks dry clothes through evaporation by wind and sunlight without consuming electricity or gas. In some states of the United States legislation protects the "right to dry" clothes. Unglazed transpired collectors (UTC) are perforated sun-facing walls used for preheating ventilation air. UTCs can raise the incoming air temperature up to 22 °C (40 °F) and deliver outlet temperatures of 45–60 °C (113–140 °F). The short payback period of transpired collectors (3 to 12 years) makes them a more cost-effective alternative than glazed collection systems. As of 2003, over 80 systems with a combined collector area of 35,000 square metres (380,000 sq ft) had been installed worldwide, including an 860 m2 (9,300 sq ft) collector in Costa Rica used for drying coffee beans and a 1,300 m2 (14,000 sq ft) collector in Coimbatore, India, used for drying marigolds.

QUES: The majority of Freemasonry considers the Liberal (Continental) strand to be Irregular, and thus withhold recognition. For the Continental lodges, however, having a different approach to Freemasonry was not a reason for severing masonic ties. In 1961, an umbrella organisation, Centre de Liaison et d'Information des Puissances maçonniques Signataires de l'Appel de Strasbourg (CLIPSAS) was set up, which today provides a forum for most of these Grand Lodges and Grand Orients worldwide. Included in the list of over 70 Grand Lodges and Grand Orients are representatives of all three of the above categories, including mixed and women's organisations. The United Grand Lodge of England does not communicate with any of these jurisdictions, and expects its allies to follow suit. This creates the distinction between Anglo-American and Continental Freemasonry.
Why was the Centre de Liasion et d'information des Puissances maconniques signataires de l'Appel de Strasbourg set up?

ANS: provides a forum for most of these Grand Lodges and Grand Orients worldwide


After working for many years at the University of Chicago, Arthur Holly Compton returned to St. Louis in 1946 to serve as Washington University's ninth chancellor. Compton reestablished the Washington University football team, making the declaration that athletics were to be henceforth played on a "strictly amateur" basis with no athletic scholarships. Under Compton’s leadership, enrollment at the University grew dramatically, fueled primarily by World War II veterans' use of their GI Bill benefits.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): In what year did Washington University's first football program get shut down?
Ah, so.. unanswerable


Question: Typically the sub-Tropical High Pressure Belt, with frequent clear skies, provides more than 300 days of sunshine per year. It is situated at the southern edge of the tropics; the Tropic of Capricorn cuts the country about in half. The winter (June – August) is generally dry, both rainy seasons occur in summer, the small rainy season between September and November, the big one between February and April. Humidity is low, and average rainfall varies from almost zero in the coastal desert to more than 600 mm in the Caprivi Strip. Rainfall is however highly variable, and droughts are common. The last[update] bad rainy season with rainfall far below the annual average occurred in summer 2006/07.
Try to answer this question if possible: When is the rainiest season in Namibia?
Answer: between February and April
