input question: Extract the answer to the question from the following context. Question: What creates fractions in this instance? Context: As an electro-magnetic wave travels through the different parts of the antenna system (radio, feed line, antenna, free space) it may encounter differences in impedance (E/H, V/I, etc.). At each interface, depending on the impedance match, some fraction of the wave's energy will reflect back to the source, forming a standing wave in the feed line. The ratio of maximum power to minimum power in the wave can be measured and is called the standing wave ratio (SWR). A SWR of 1:1 is ideal. A SWR of 1.5:1 is considered to be marginally acceptable in low power applications where power loss is more critical, although an SWR as high as 6:1 may still be usable with the right equipment. Minimizing impedance differences at each interface (impedance matching) will reduce SWR and maximize power transfer through each part of the antenna system.???
output answer: The ratio of maximum power to minimum power
Extract the answer to the question from the following context. Question: If two places are further apart, what will there be more of in terms of dialect? Context: South Slavic historically formed a dialect continuum, i.e. each dialect has some similarities with the neighboring one, and differences grow with distance. However, migrations from the 16th to 18th centuries resulting from the spread of Ottoman Empire on the Balkans have caused large-scale population displacement that broke the dialect continuum into many geographical pockets. Migrations in the 20th century, primarily caused by urbanization and wars, also contributed to the reduction of dialectal differences.

Answer: differences
Q: Extract the answer to the question from the following context. Question: How was "Works in Architecture" released? Context: A new phase in neoclassical design was inaugurated by Robert and James Adam, who travelled in Italy and Dalmatia in the 1750s, observing the ruins of the classical world. On their return to Britain, they published a book entitled The Works in Architecture in installments between 1773 and 1779. This book of engraved designs made the Adam repertory available throughout Europe. The Adam brothers aimed to simplify the rococo and baroque styles which had been fashionable in the preceding decades, to bring what they felt to be a lighter and more elegant feel to Georgian houses. The Works in Architecture illustrated the main buildings the Adam brothers had worked on and crucially documented the interiors, furniture and fittings, designed by the Adams.
A: in installments
Question: Extract the answer to the question from the following context. Question: Who is Plato? Context: Aristotle of Stagira, the most important disciple of Plato, shared with his teacher the title of the greatest philosopher of antiquity. But while Plato had sought to elucidate and explain things from the supra-sensual standpoint of the forms, his pupil preferred to start from the facts given us by experience. Except from these three most significant Greek philosophers other known schools of Greek philosophy from other founders during ancient times were Stoicism, Epicureanism, Skepticism and Neoplatonism.
Answer: the greatest philosopher of antiquity
[Q]: Extract the answer to the question from the following context. Question: How was Euthydemus threatened? Context: The Greek kingdom of Bactria began as a breakaway satrapy of the Seleucid empire, which, because of the size of the empire, had significant freedom from central control. Between 255-246 BCE, the governor of Bactria, Sogdiana and Margiana (most of present-day Afghanistan), one Diodotus, took this process to its logical extreme and declared himself king. Diodotus II, son of Diodotus, was overthrown in about 230 BC by Euthydemus, possibly the satrap of Sogdiana, who then started his own dynasty. In c. 210 BC, the Greco-Bactrian kingdom was invaded by a resurgent Seleucid empire under Antiochus III. While victorious in the field, it seems Antiochus came to realise that there were advantages in the status quo (perhaps sensing that Bactria could not be governed from Syria), and married one of his daughters to Euthydemus's son, thus legitimising the Greco-Bactria dynasty. Soon afterwards the Greco-Bactrian kingdom seems to have expanded, possibly taking advantage of the defeat of the Parthian king Arsaces II by Antiochus.

Problem: Given the question: Extract the answer to the question from the following context. Question: What is Alaska not included in when referencing the US? Context: Alaska is the northernmost and westernmost state in the United States and has the most easterly longitude in the United States because the Aleutian Islands extend into the eastern hemisphere. Alaska is the only non-contiguous U.S. state on continental North America; about 500 miles (800 km) of British Columbia (Canada) separates Alaska from Washington. It is technically part of the continental U.S., but is sometimes not included in colloquial use; Alaska is not part of the contiguous U.S., often called "the Lower 48". The capital city, Juneau, is situated on the mainland of the North American continent but is not connected by road to the rest of the North American highway system.

The answer is:
the Lower 48
