QUES: Kerry's paternal grandparents, shoe businessman Frederick A. "Fred" Kerry and musician Ida Lowe, were immigrants from the Austro-Hungarian Empire. Fred was born as "Fritz Kohn" before he and Ida took on the "Kerry" name and moved to the United States. Fred and Ida were born Jewish, and converted to Catholicism together in Austria. His maternal ancestors were of Scottish and English descent, and his maternal grandfather James Grant Forbes II was a member of the Forbes family, while his maternal grandmother Margaret Tyndal Winthrop was a member of the DudleyWinthrop family. Margaret's paternal grandfather Robert Charles Winthrop served as the 22nd Speaker of the U.S. House of Representatives. Robert's father was Governor Thomas Lindall Winthrop. Thomas' father John Still Winthrop was a great-great-grandson of Massachusetts Bay Colony Governor John Winthrop and great-grandson of Governor Thomas Dudley.

QUES: Zinc is a chemical element with symbol Zn and atomic number 30. It is the first element of group 12 of the periodic table. In some respects zinc is chemically similar to magnesium: its ion is of similar size and its only common oxidation state is +2. Zinc is the 24th most abundant element in Earth's crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest mineable amounts are found in Australia, Asia, and the United States. Zinc production includes froth flotation of the ore, roasting, and final extraction using electricity (electrowinning).
What is used to extract zinc during the production process?

ANS: electricity

QUES: The British dealt with range measurement first, when it was realised that range was the key to producing a better fuse setting. This led to the Height/Range Finder (HRF), the first model being the Barr & Stroud UB2, a 2-metre optical coincident rangefinder mounted on a tripod. It measured the distance to the target and the elevation angle, which together gave the height of the aircraft. These were complex instruments and various other methods were also used. The HRF was soon joined by the Height/Fuse Indicator (HFI), this was marked with elevation angles and height lines overlaid with fuse length curves, using the height reported by the HRF operator, the necessary fuse length could be read off.
What helped with better fuse setting?

ANS: range measurement

QUES: Extended systems of underwater caves, sinkholes and springs are found throughout the state and supply most of the water used by residents. The limestone is topped with sandy soils deposited as ancient beaches over millions of years as global sea levels rose and fell. During the last glacial period, lower sea levels and a drier climate revealed a much wider peninsula, largely savanna. The Everglades, an enormously wide, slow-flowing river encompasses the southern tip of the peninsula. Sinkhole damage claims on property in the state exceeded a total of $2 billion from 2006 through 2010.
What is the river through the Northern area of Florida?
