Problem: AOC Bomber Command Arthur Harris did see German morale as a major objective. However, he did not believe that the morale-collapse could occur without the destruction of the German economy. The primary goal of Bomber Command's offensives was to destroy the German industrial base (economic warfare), and in doing so reduce morale. In late 1943, just before the Battle of Berlin, he declared the power of Bomber Command would enable it to achieve "a state of devastation in which surrender is inevitable." A summary of Harris' strategic intentions was clear:
Without what could morale collapse occur according to Arthur Harris?
The answer is the following: without the destruction of the German economy.

Problem: The institutes of technology and polytechnics have been in existence since at least the 18th century, but became popular after World War II with the expansion of engineering and applied science education, associated with the new needs created by industrialization. The world's first institution of technology, the Berg-Schola (today its legal successor is the University of Miskolc) was founded by the Court Chamber of Vienna in Selmecbanya, Kingdom of Hungary in 1735 in order to train specialists of precious metal and copper mining according to the requirements of the industrial revolution in Hungary. The oldest German Institute of Technology is the Braunschweig University of Technology (founded in 1745 as "Collegium Carolinum"). Another exception is the Ecole Polytechnique, which has educated French elites since its foundation in 1794. In some cases, polytechnics or institutes of technology are engineering schools or technical colleges.
In what year was the Ecole Polytechnique founded?
The answer is the following: 1794

Problem: A famous example of Arabic poetry and Persian poetry on romance (love) is Layla and Majnun, dating back to the Umayyad era in the 7th century. It is a tragic story of undying love much like the later Romeo and Juliet, which was itself said to have been inspired by a Latin version of Layla and Majnun to an extent. Ferdowsi's Shahnameh, the national epic of Iran, is a mythical and heroic retelling of Persian history. Amir Arsalan was also a popular mythical Persian story, which has influenced some modern works of fantasy fiction, such as The Heroic Legend of Arslan.
Who wrote Shahnameh?
The answer is the following: Ferdowsi

Problem: People with prolonged, frequent, or close contact with people with TB are at particularly high risk of becoming infected, with an estimated 22% infection rate. A person with active but untreated tuberculosis may infect 1015 (or more) other people per year. Transmission should occur from only people with active TB those with latent infection are not thought to be contagious. The probability of transmission from one person to another depends upon several factors, including the number of infectious droplets expelled by the carrier, the effectiveness of ventilation, the duration of exposure, the virulence of the M. tuberculosis strain, the level of immunity in the uninfected person, and others. The cascade of person-to-person spread can be circumvented by segregating those with active ("overt") TB and putting them on anti-TB drug regimens. After about two weeks of effective treatment, subjects with nonresistant active infections generally do not remain contagious to others. If someone does become infected, it typically takes three to four weeks before the newly infected person becomes infectious enough to transmit the disease to others.
If you're around someone with active TB, what's the chance you'll contract it expressed as a percentage?
The answer is the following:
22%
