In general, USB cables have only plugs on their ends, while hosts and devices have only receptacles. Hosts almost universally have Type-A receptacles, while devices have one or another Type-B variety. Type-A plugs mate only with Type-A receptacles, and the same applies to their Type-B counterparts; they are deliberately physically incompatible. However, an extension to the USB standard specification called USB On-The-Go (OTG) allows a single port to act as either a host or a device, which is selectable by the end of the cable that plugs into the receptacle on the OTG-enabled unit. Even after the cable is hooked up and the units are communicating, the two units may "swap" ends under program control. This capability is meant for units such as PDAs in which the USB link might connect to a PC's host port as a device in one instance, yet connect as a host itself to a keyboard and mouse device in another instance.
Hosts almost always have what type of receptacle?
****
The answer: Type-A receptacles

An 1855 paper on the "introduction" of species, written by Alfred Russel Wallace, claimed that patterns in the geographical distribution of living and fossil species could be explained if every new species always came into existence near an already existing, closely related species. Charles Lyell recognised the implications of Wallace's paper and its possible connection to Darwin's work, although Darwin did not, and in a letter written on 12 May 1856 Lyell urged Darwin to publish his theory to establish priority. Darwin was torn between the desire to set out a full and convincing account and the pressure to quickly produce a short paper. He met Lyell, and in correspondence with Joseph Dalton Hooker affirmed that he did not want to expose his ideas to review by an editor as would have been required to publish in an academic journal. He began a "sketch" account on 14 May 1856, and by July had decided to produce a full technical treatise on species. His theory including the principle of divergence was complete by 5 September 1857 when he sent Asa Gray a brief but detailed abstract of his ideas.
When was the "Introduction of Species" paper written?
****
The answer: 1855

To the west, settlements in the Zagros basin experience lower temperatures, severe winters with below zero average daily temperatures and heavy snowfall. The eastern and central basins are arid, with less than 200 mm (7.9 in) of rain, and have occasional deserts. Average summer temperatures rarely exceed 38 C (100.4 F). The coastal plains of the Persian Gulf and Gulf of Oman in southern Iran have mild winters, and very humid and hot summers. The annual precipitation ranges from 135 to 355 mm (5.3 to 14.0 in).
In Iran's western Zagros Basin, what are the average daily temperatures during winter?
****
The answer: below zero

On 11 July, Nasser replaced Amer with Mohamed Fawzi as general commander, over the protestations of Amer's loyalists in the military, 600 of whom marched on army headquarters and demanded Amer's reinstatement. After Nasser sacked thirty of the loyalists in response, Amer and his allies devised a plan to topple him on 27 August. Nasser was tipped off about their activities and, after several invitations, he convinced Amer to meet him at his home on 24 August. Nasser confronted Amer about the coup plot, which he denied before being arrested by Mohieddin. Amer committed suicide on 14 September. Despite his souring relationship with Amer, Nasser spoke of losing "the person closest to [him]". Thereafter, Nasser began a process of depoliticizing the armed forces, arresting dozens of leading military and intelligence figures loyal to Amer.
How did Nasser try to deal with the military following the coup attempt?
****
The answer:
depoliticizing the armed forces
