Article: Ethernet standards require electrical isolation between the networked device (computer, phone, etc.) and the network cable up to 1500 V AC or 2250 V DC for 60 seconds. USB has no such requirement as it was designed for peripherals closely associated with a host computer, and in fact it connects the peripheral and host grounds. This gives Ethernet a significant safety advantage over USB with peripherals such as cable and DSL modems connected to external wiring that can assume hazardous voltages under certain fault conditions.

Question: USB connects what?
Ans: the peripheral and host grounds


Article: As part of this Popular Revolution, Gaddafi invited Libya's people to found General People's Committees as conduits for raising political consciousness. Although offering little guidance for how to set up these councils, Gaddafi claimed that they would offer a form of direct political participation that was more democratic than a traditional party-based representative system. He hoped that the councils would mobilize the people behind the RCC, erode the power of the traditional leaders and the bureaucracy, and allow for a new legal system chosen by the people.

Question: Along with the bureaucracy, who were the General People's Committees directed at?
Ans: traditional leaders


Article: The economy began to recover in the early 1960s, and the city experienced explosive population growth through immigration spurred by the jobs created with the implementation of major urban projects and infrastructure improvements. With the advent of democracy in Spain, the ancient kingdom of Valencia was established as a new autonomous entity, the Valencian Community, the Statute of Autonomy of 1982 designating Valencia as its capital. On the night of 23 February 1981, shortly after Antonio Tejero had stormed Congress, the Captain General of the Third Military Region, Jaime Milans del Bosch, rose up in Valencia, put tanks on the streets, declared a state of emergency and tried to convince other senior military figures to support the coup. After the televised message of King Juan Carlos I, those in the military who had not yet aligned themselves decided to remain loyal to the government, and the coup failed. Despite this lack of support, Milans del Bosch only surrendered at 5 a.m. on the next day, 24 February.

Question: Who led a coup in Valencia?
Ans: Jaime Milans del Bosch


Article: Maternal factors also play a role in the body’s immune response. At birth, most of the immunoglobulin present is maternal IgG. Because IgM, IgD, IgE and IgA don’t cross the placenta, they are almost undetectable at birth. Some IgA is provided by breast milk. These passively-acquired antibodies can protect the newborn for up to 18 months, but their response is usually short-lived and of low affinity. These antibodies can also produce a negative response. If a child is exposed to the antibody for a particular antigen before being exposed to the antigen itself then the child will produce a dampened response. Passively acquired maternal antibodies can suppress the antibody response to active immunization. Similarly the response of T-cells to vaccination differs in children compared to adults, and vaccines that induce Th1 responses in adults do not readily elicit these same responses in neonates. Between six to nine months after birth, a child’s immune system begins to respond more strongly to glycoproteins, but there is usually no marked improvement in their response to polysaccharides until they are at least one year old. This can be the reason for distinct time frames found in vaccination schedules.

Question: Newborns can acquire antibodies from the mother through what means?
Ans:
breast milk
