Problem: Many early 19th-century neoclassical architects were influenced by the drawings and projects of Etienne-Louis Boullee and Claude Nicolas Ledoux. The many graphite drawings of Boullee and his students depict spare geometrical architecture that emulates the eternality of the universe. There are links between Boullee's ideas and Edmund Burke's conception of the sublime. Ledoux addressed the concept of architectural character, maintaining that a building should immediately communicate its function to the viewer: taken literally such ideas give rise to "architecture parlante".
What concept did Ledoux address?
The answer is the following: architectural character

Problem: Freemasonry consists of fraternal organisations that trace their origins to the local fraternities of stonemasons, which from the end of the fourteenth century regulated the qualifications of stonemasons and their interaction with authorities and clients. The degrees of freemasonry retain the three grades of medieval craft guilds, those of Apprentice, Journeyman or fellow (now called Fellowcraft), and Master Mason. These are the degrees offered by Craft (or Blue Lodge) Freemasonry. Members of these organisations are known as Freemasons or Masons. There are additional degrees, which vary with locality and jurisdiction, and are usually administered by different bodies than the craft degrees.
How many grades are there in medieval craft guilds?
The answer is the following: three grades

Problem: In 1972, Walter Fiers and his team at the University of Ghent were the first to determine the sequence of a gene: the gene for Bacteriophage MS2 coat protein. The subsequent development of chain-termination DNA sequencing in 1977 by Frederick Sanger improved the efficiency of sequencing and turned it into a routine laboratory tool. An automated version of the Sanger method was used in early phases of the Human Genome Project.
What did the devlopment of the chain termination DNA sequencing method do for the sequencing process?
The answer is the following: improved the efficiency of sequencing and turned it into a routine laboratory tool.

Problem: On 25 February 1954, Naguib announced his resignation after the RCC held an official meeting without his presence two days prior. On 26 February, Nasser accepted the resignation, put Naguib under house arrest, and the RCC proclaimed Nasser as both RCC chairman and prime minister. As Naguib intended, a mutiny immediately followed, demanding Naguib's reinstatement and the RCC's dissolution. While visiting the striking officers at Military Headquarters (GHQ) to call for the mutiny's end, Nasser was initially intimidated into accepting their demands. However, on 27 February, Nasser's supporters in the army launched a raid on the GHQ, ending the mutiny. Later that day, hundreds of thousands of protesters, mainly belonging to the Brotherhood, called for Naguib's return and Nasser's imprisonment. In response, a sizable group within the RCC, led by Khaled Mohieddin, demanded Naguib's release and return to the presidency. Nasser was forced to acquiesce, but delayed Naguib's reinstatement until 4 March, allowing him to promote Amer to Commander of the Armed Forcesa position formerly occupied by Naguib.
Who did Nasser promote to armed forces commander?
The answer is the following:
Amer
