Article: For instance, to look up the character where the sound is not known, e.g., (pine tree), the user first determines which part of the character is the radical (here ), then counts the number of strokes in the radical (four), and turns to the radical index (usually located on the inside front or back cover of the dictionary). Under the number "4" for radical stroke count, the user locates , then turns to the page number listed, which is the start of the listing of all the characters containing this radical. This page will have a sub-index giving remainder stroke numbers (for the non-radical portions of characters) and page numbers. The right half of the character also contains four strokes, so the user locates the number 4, and turns to the page number given. From there, the user must scan the entries to locate the character he or she is seeking. Some dictionaries have a sub-index which lists every character containing each radical, and if the user knows the number of strokes in the non-radical portion of the character, he or she can locate the correct page directly.

Question: What do some dictionaries have?
Ans: sub-index

Here is a question about this article: After having declined in size following the subjugation of the Mediterranean, the Roman navy underwent short-term upgrading and revitalisation in the late Republic to meet several new demands. Under Caesar, an invasion fleet was assembled in the English Channel to allow the invasion of Britannia; under Pompey, a large fleet was raised in the Mediterranean Sea to clear the sea of Cilician pirates. During the civil war that followed, as many as a thousand ships were either constructed or pressed into service from Greek cities.
What is the answer to this question: In which sea was a large amount of naval vessels sent in order to remove Cilician pirates?
****
So... Mediterranean Sea

Welsh sides that play in English leagues are eligible, although since the creation of the League of Wales there are only six clubs remaining: Cardiff City (the only non-English team to win the tournament, in 1927), Swansea City, Newport County, Wrexham, Merthyr Town and Colwyn Bay. In the early years other teams from Wales, Ireland and Scotland also took part in the competition, with Glasgow side Queen's Park losing the final to Blackburn Rovers in 1884 and 1885 before being barred from entering by the Scottish Football Association. In the 201314 season the first Channel Island club entered the competition when Guernsey F.C. competed for the first time.
May Welsh clubs enter the competition?

Problem: Please answer a question about the following article about Beer:
The first step, where the wort is prepared by mixing the starch source (normally malted barley) with hot water, is known as "mashing". Hot water (known as "liquor" in brewing terms) is mixed with crushed malt or malts (known as "grist") in a mash tun. The mashing process takes around 1 to 2 hours, during which the starches are converted to sugars, and then the sweet wort is drained off the grains. The grains are now washed in a process known as "sparging". This washing allows the brewer to gather as much of the fermentable liquid from the grains as possible. The process of filtering the spent grain from the wort and sparge water is called wort separation. The traditional process for wort separation is lautering, in which the grain bed itself serves as the filter medium. Some modern breweries prefer the use of filter frames which allow a more finely ground grist.
In brewing, what do starches become during the mashing process?
A: sugars

Question: Read this and answer the question

John's personal life greatly affected his reign. Contemporary chroniclers state that John was sinfully lustful and lacking in piety. It was common for kings and nobles of the period to keep mistresses, but chroniclers complained that John's mistresses were married noblewomen, which was considered unacceptable. John had at least five children with mistresses during his first marriage to Isabelle of Gloucester, and two of those mistresses are known to have been noblewomen. John's behaviour after his second marriage to Isabella of Angouleme is less clear, however. None of John's known illegitimate children were born after he remarried, and there is no actual documentary proof of adultery after that point, although John certainly had female friends amongst the court throughout the period. The specific accusations made against John during the baronial revolts are now generally considered to have been invented for the purposes of justifying the revolt; nonetheless, most of John's contemporaries seem to have held a poor opinion of his sexual behaviour.[nb 14]

Many of John's mistresses were what?
Answer: married noblewomen

The two mature piano sonatas (No. 2, Op. 35, written in 1839 and No. 3, Op. 58, written in 1844) are in four movements. In Op. 35, Chopin was able to combine within a formal large musical structure many elements of his virtuosic piano technique"a kind of dialogue between the public pianism of the brilliant style and the German sonata principle". The last movement, a brief (75-bar) perpetuum mobile in which the hands play in unmodified octave unison throughout, was found shocking and unmusical by contemporaries, including Schumann. The Op. 58 sonata is closer to the German tradition, including many passages of complex counterpoint, "worthy of Brahms" according to the music historians Kornel Michaowski and Jim Samson.
How many movements are No. 2, Op. 35 and No. 3, Op 58 in?
four
