In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

The second Multilingual European subset includes everything from which other Unicode subsets?, Context: Several subsets of Unicode are standardized: Microsoft Windows since Windows NT 4.0 supports WGL-4 with 652 characters, which is considered to support all contemporary European languages using the Latin, Greek, or Cyrillic script. Other standardized subsets of Unicode include the Multilingual European Subsets: MES-1 (Latin scripts only, 335 characters), MES-2 (Latin, Greek and Cyrillic 1062 characters) and MES-3A & MES-3B (two larger subsets, not shown here). Note that MES-2 includes every character in MES-1 and WGL-4.

What is reduced by playback equipment?, Context: Due to recording mastering and manufacturing limitations, both high and low frequencies were removed from the first recorded signals by various formulae. With low frequencies, the stylus must swing a long way from side to side, requiring the groove to be wide, taking up more space and limiting the playing time of the record. At high frequencies, hiss, pops, and ticks are significant. These problems can be reduced by using equalization to an agreed standard. During recording the amplitude of low frequencies is reduced, thus reducing the groove width required, and the amplitude at high frequencies is increased. The playback equipment boosts bass and cuts treble so as to restore the tonal balance in the original signal; this also reduces the high frequency noise. Thus more music will fit on the record, and noise is reduced.

Besides sending a ship to the Black Sea, what else prompted the creating of the treaty confirming that France and the Roman Catholic Church would be the supreme Christian authority?, Context: Napoleon III responded with a show of force, sending the ship of the line Charlemagne to the Black Sea. This action was a violation of the London Straits Convention.:104:19 Thus, France's show of force presented a real threat, and when combined with aggressive diplomacy and money, induced the Ottoman Sultan Abdülmecid I to accept a new treaty, confirming France and the Roman Catholic Church as the supreme Christian authority with control over the Roman Catholic holy places and possession of the keys to the Church of the Nativity, previously held by the Greek Orthodox Church.:20
