Article: The company, which benefited from the imperial patronage, soon expanded its commercial trading operations, eclipsing the Portuguese Estado da India, which had established bases in Goa, Chittagong, and Bombay, which Portugal later ceded to England as part of the dowry of Catherine de Braganza. The East India Company also launched a joint attack with the Dutch United East India Company on Portuguese and Spanish ships off the coast of China, which helped secure their ports in China. The company established trading posts in Surat (1619), Madras (1639), Bombay (1668), and Calcutta (1690). By 1647, the company had 23 factories, each under the command of a factor or master merchant and governor if so chosen, and 90 employees in India. The major factories became the walled forts of Fort William in Bengal, Fort St George in Madras, and Bombay Castle.

Question: The top or most important factories had what physical feature in common?
Ans: walled forts

Here is a question about this article: In species which show a distinct difference between heartwood and sapwood the natural color of heartwood is usually darker than that of the sapwood, and very frequently the contrast is conspicuous (see section of yew log above). This is produced by deposits in the heartwood of chemical substances, so that a dramatic color difference does not mean a dramatic difference in the mechanical properties of heartwood and sapwood, although there may be a dramatic chemical difference.
What is the answer to this question: Is the color difference between heartwood and sapwood usually very subtle or conspicuous?
****
So... conspicuous

The problem: Answer a question about this article:
Under the doctrine of Erie Railroad Co. v. Tompkins (1938), there is no general federal common law. Although federal courts can create federal common law in the form of case law, such law must be linked one way or another to the interpretation of a particular federal constitutional provision, statute, or regulation (which in turn was enacted as part of the Constitution or after). Federal courts lack the plenary power possessed by state courts to simply make up law, which the latter are able to do in the absence of constitutional or statutory provisions replacing the common law. Only in a few narrow limited areas, like maritime law, has the Constitution expressly authorized the continuation of English common law at the federal level (meaning that in those areas federal courts can continue to make law as they see fit, subject to the limitations of stare decisis).
When are states allowed to use plenary power?
****
The answer: absence of constitutional or statutory provisions replacing the common law

Problem: Please answer a question about the following article about Wood:
During the development of a tree, the lower limbs often die, but may remain attached for a time, sometimes years. Subsequent layers of growth of the attaching stem are no longer intimately joined with the dead limb, but are grown around it. Hence, dead branches produce knots which are not attached, and likely to drop out after the tree has been sawn into boards.
For what length of time can a dead lower limb stay attached to a tree?
A: years
