Here is a question about this article: Although it had equipment capable of doing serious damage, the problem for the Luftwaffe was its unclear strategy and poor intelligence. OKL had not been informed that Britain was to be considered a potential opponent until early 1938. It had no time to gather reliable intelligence on Britain's industries. Moreover, OKL could not settle on an appropriate strategy. German planners had to decide whether the Luftwaffe should deliver the weight of its attacks against a specific segment of British industry such as aircraft factories, or against a system of interrelated industries such as Britain's import and distribution network, or even in a blow aimed at breaking the morale of the British population. The Luftwaffe's strategy became increasingly aimless over the winter of 19401941. Disputes among the OKL staff revolved more around tactics than strategy. This method condemned the offensive over Britain to failure before it began.
What is the answer to this question: What did the disputes between the staff cause to happen to the strategy against Britain?
****
So... failure before it began

Here is a question about this article: The Heptanesean kantadhes ( 'serenades'; sing.: ) became the forerunners of the Greek modern song, influencing its development to a considerable degree. For the first part of the next century, several Greek composers continued to borrow elements from the Heptanesean style. The most successful songs during the period 18701930 were the so-called Athenian serenades, and the songs performed on stage ( 'theatrical revue songs') in revue, operettas and nocturnes that were dominating Athens' theater scene.
What is the answer to this question: Athenian serenades were most successful during what time period?
****
So... 18701930

Here is a question about this article: The Mantoux tuberculin skin test is often used to screen people at high risk for TB. Those who have been previously immunized may have a false-positive test result. The test may be falsely negative in those with sarcoidosis, Hodgkin's lymphoma, malnutrition, and most notably, active tuberculosis. Interferon gamma release assays (IGRAs), on a blood sample, are recommended in those who are positive to the Mantoux test. These are not affected by immunization or most environmental mycobacteria, so they generate fewer false-positive results. However, they are affected by M. szulgai, M. marinum, and M. kansasii. IGRAs may increase sensitivity when used in addition to the skin test, but may be less sensitive than the skin test when used alone.
What is the answer to this question: Which test has fewer false positives: IGRAs or the Mantoux skin test?
****
So...
IGRAs
