Problem: ASCII:

Originally based on the English alphabet, ASCII encodes 128 specified characters into seven-bit integers as shown by the ASCII chart on the right. The characters encoded are numbers 0 to 9, lowercase letters a to z, uppercase letters A to Z, basic punctuation symbols, control codes that originated with Teletype machines, and a space. For example, lowercase j would become binary 1101010 and decimal 106. ASCII includes definitions for 128 characters: 33 are non-printing control characters (many now obsolete) that affect how text and space are processed and 95 printable characters, including the space (which is considered an invisible graphic:223).

How many characters are printable characters? 
---
A: 95 printable characters


Problem: Egypt:

The First Intermediate Period ushered in a time of political upheaval for about 150 years. Stronger Nile floods and stabilisation of government, however, brought back renewed prosperity for the country in the Middle Kingdom c. 2040 BC, reaching a peak during the reign of Pharaoh Amenemhat III. A second period of disunity heralded the arrival of the first foreign ruling dynasty in Egypt, that of the Semitic Hyksos. The Hyksos invaders took over much of Lower Egypt around 1650 BC and founded a new capital at Avaris. They were driven out by an Upper Egyptian force led by Ahmose I, who founded the Eighteenth Dynasty and relocated the capital from Memphis to Thebes.

What was the first foreign ruling dynasty of Egypt?
---
A: Semitic Hyksos


Problem: Infection:

Complex serological techniques have been developed into what are known as Immunoassays. Immunoassays can use the basic antibody – antigen binding as the basis to produce an electro - magnetic or particle radiation signal, which can be detected by some form of instrumentation. Signal of unknowns can be compared to that of standards allowing quantitation of the target antigen. To aid in the diagnosis of infectious diseases, immunoassays can detect or measure antigens from either infectious agents or proteins generated by an infected organism in response to a foreign agent. For example, immunoassay A may detect the presence of a surface protein from a virus particle. Immunoassay B on the other hand may detect or measure antibodies produced by an organism's immune system that are made to neutralize and allow the destruction of the virus.

What stops quantitation of the target antigen?
---
A: unanswerable


Problem: Comics:

Gag and editorial cartoons usually consist of a single panel, often incorporating a caption or speech balloon. Definitions of comics which emphasize sequence usually exclude gag, editorial, and other single-panel cartoons; they can be included in definitions that emphasize the combination of word and image. Gag cartoons first began to proliferate in broadsheets published in Europe in the 18th and 19th centuries, and the term "cartoon"[h] was first used to describe them in 1843 in the British humour magazine Punch.

When did gag single-panel illustrations become known as cartoons?
---
A:
1843
