QUES: In 1897, Frank Shuman, a U.S. inventor, engineer and solar energy pioneer built a small demonstration solar engine that worked by reflecting solar energy onto square boxes filled with ether, which has a lower boiling point than water, and were fitted internally with black pipes which in turn powered a steam engine. In 1908 Shuman formed the Sun Power Company with the intent of building larger solar power plants. He, along with his technical advisor A.S.E. Ackermann and British physicist Sir Charles Vernon Boys, developed an improved system using mirrors to reflect solar energy upon collector boxes, increasing heating capacity to the extent that water could now be used instead of ether. Shuman then constructed a full-scale steam engine powered by low-pressure water, enabling him to patent the entire solar engine system by 1912.

QUES: On July 8, 2007 The Washington Post published excerpts from UCLA Professor Amy Zegart's book Spying Blind: The CIA, the FBI, and the Origins of 9/11. The Post reported from Zegart's book that government documents show the CIA and FBI missed 23 potential chances to disrupt the terrorist attacks of September 11, 2001. The primary reasons for the failures included: agency cultures resistant to change and new ideas; inappropriate incentives for promotion; and a lack of cooperation between the FBI, CIA and the rest of the United States Intelligence Community. The book blamed the FBI's decentralized structure, which prevented effective communication and cooperation among different FBI offices. The book suggested that the FBI has not evolved into an effective counter-terrorism or counter-intelligence agency, due in large part to deeply ingrained agency cultural resistance to change. For example, FBI personnel practices continue to treat all staff other than special agents as support staff, classifying intelligence analysts alongside the FBI's auto mechanics and janitors.

What two agencies had a lack of co-operation?
What is the answer?
ANS: FBI, CIA
QUES: Both languages are still largely mutually intelligible, although this relation can in some fields (such as lexicon, spelling and grammar) be asymmetric, as it is easier for Dutch speakers to understand written Afrikaans than it is for Afrikaans speakers to understand written Dutch. Afrikaans is grammatically far less complex than Dutch, and vocabulary items are generally altered in a clearly patterned manner, e.g. vogel becomes voël ("bird") and regen becomes reën ("rain"). In South Africa, the number of students following Dutch at university, is difficult to estimate, since the academic study of Afrikaans inevitably includes the study of Dutch. Elsewhere in the world, the number of people learning Dutch is relatively small.

Is it difficult or easy to estimate the number of students in South Africa who study Dutch?
