Problem: USB:

USB 2.0 provides for a maximum cable length of 5 meters for devices running at Hi Speed (480 Mbit/s). The primary reason for this limit is the maximum allowed round-trip delay of about 1.5 s. If USB host commands are unanswered by the USB device within the allowed time, the host considers the command lost. When adding USB device response time, delays from the maximum number of hubs added to the delays from connecting cables, the maximum acceptable delay per cable amounts to 26 ns. The USB 2.0 specification requires that cable delay be less than 5.2 ns per meter (192 000 km/s, which is close to the maximum achievable transmission speed for standard copper wire).

How long is the maximum cable length the USB 2.0 provides?

A: 5 meters for devices running at Hi Speed

Problem: The sociology of culture grew from the intersection between sociology (as shaped by early theorists like Marx, Durkheim, and Weber) with the growing discipline of anthropology, where in researchers pioneered ethnographic strategies for describing and analyzing a variety of cultures around the world. Part of the legacy of the early development of the field lingers in the methods (much of cultural sociological research is qualitative), in the theories (a variety of critical approaches to sociology are central to current research communities), and in the substantive focus of the field. For instance, relationships between popular culture, political control, and social class were early and lasting concerns in the field.
Which three early theorists helped eliminate the sociology of culture?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Bacteria can be grown in the laboratory on nutrient culture media, but viruses need living cells in which to replicate. Many vaccines to infectious diseases can be grown in fertilised chicken eggs. Millions of eggs are used each year to generate the annual flu vaccine requirements, a complex process that takes about six months after the decision is made as to what strains of virus to include in the new vaccine. A problem with using eggs for this purpose is that people with egg allergies are unable to be immunised, but this disadvantage may be overcome as new techniques for cell-based rather than egg-based culture become available. Cell-based culture will also be useful in a pandemic when it may be difficult to acquire a sufficiently large quantity of suitable sterile, fertile eggs.
How long does it take for the flu vaccine to be fully ready for deployment into the population ?
A: process that takes about six months

Context and question: Winters are cold and damp, and prevailing wind patterns that blow offshore minimize the moderating effects of the Atlantic Ocean; yet the Atlantic and the partial shielding from colder air by the Appalachians keep the city warmer in the winter than inland North American cities at similar or lesser latitudes such as Pittsburgh, Cincinnati, and Indianapolis. The daily mean temperature in January, the area's coldest month, is 32.6 F (0.3 C); however, temperatures usually drop to 10 F (12 C) several times per winter, and reach 50 F (10 C) several days each winter month. Spring and autumn are unpredictable and can range from chilly to warm, although they are usually mild with low humidity. Summers are typically warm to hot and humid, with a daily mean temperature of 76.5 F (24.7 C) in July and an average humidity level of 72%. Nighttime conditions are often exacerbated by the urban heat island phenomenon, while daytime temperatures exceed 90 F (32 C) on average of 17 days each summer and in some years exceed 100 F (38 C). In the warmer months, the dew point, a measure of atmospheric moisture, ranges from 57.3 F (14.1 C) in June to 62.0 F (16.7 C) in August. Extreme temperatures have ranged from 15 F (26 C), recorded on February 9, 1934, up to 106 F (41 C) on July 9, 1936.
What is the average humidity in July as a percentage?
Answer: 72%

Question: Marine mammals are many, such as the dolphins, porpoises and whales, which are seen here during the migration period from December till May. Turtles are a common sight along the coastline of the island. They are a protected species and in the endangered list. It is stated that it will take 1550 years for this species to attain reproductive age. Though they live in the sea, the females come to the shore to lay eggs and are protected by private societies. Three species of turtles are particularly notable. These are: The leatherback sea turtles which have leather skin instead of a shell and are the largest of the type found here, some times measuring a much as 3 m (average is about 1.5 m) and weighing about 450 kg (jellyfish is their favourite diet); the hawksbill turtles, which have hawk-like beaks and found near reefs, generally about 90 cm in diameter and weigh about 60 kg and their diet consists of crabs and snails; and the green turtles, herbivores which have rounded heads, generally about 90 cm in diameter and live amidst tall sea grasses.
Is there an answer to this question: What does a whales diet consist of?

Answer: unanswerable

The second Diadochi war began following the death of Antipater in 319 BC. Passing over his own son, Cassander, Antipater had declared Polyperchon his successor as Regent. Cassander rose in revolt against Polyperchon (who was joined by Eumenes) and was supported by Antigonus, Lysimachus and Ptolemy. In 317, Cassander invaded Macedonia, attaining control of Macedon, sentencing Olympias to death and capturing the boy king Alexander IV, and his mother. In Asia, Eumenes was betrayed by his own men after years of campaign and was given up to Antigonus who had him executed.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who did Antipater declar as his successor?
Ah, so..
Polyperchon
