Problem: The Medieval period includes music from after the fall of Rome to about 1400. Monophonic chant, also called plainsong or Gregorian chant, was the dominant form until about 1100. Polyphonic (multi-voiced) music developed from monophonic chant throughout the late Middle Ages and into the Renaissance, including the more complex voicings of motets.

Answer: Monophonic chant

Problem: Local train services operate in the central, southern and eastern sections of the city and are operated by South West Trains, with stations at Swaythling, St Denys, Millbrook, Redbridge, Bitterne, Sholing and Woolston. Plans were announced by Hampshire County Council in July 2009 for the introduction of tram-train running from Hythe (on what is now a freight-only line to Fawley) via Totton to Southampton Central Station and on to Fareham via St. Denys, and Swanwick. The proposal follows a failed plan to bring light rail to the Portsmouth and Gosport areas in 2005.
What's the current destination of the freight-only line the Hampshire County Council wants to use to expand passenger service?

Answer: Fawley

Problem: The radiation of many antennas shows a pattern of maxima or "lobes" at various angles, separated by "nulls", angles where the radiation falls to zero. This is because the radio waves emitted by different parts of the antenna typically interfere, causing maxima at angles where the radio waves arrive at distant points in phase, and zero radiation at other angles where the radio waves arrive out of phase. In a directional antenna designed to project radio waves in a particular direction, the lobe in that direction is designed larger than the others and is called the "main lobe". The other lobes usually represent unwanted radiation and are called "sidelobes". The axis through the main lobe is called the "principal axis" or "boresight axis".
What is the main distinction of side lobes?

Answer:
represent unwanted radiation
