Following news that combined OttomanEgyptian fleets were going to attack the Greek island of Hydra, the allied fleet intercepted the OttomanEgyptian fleet at Navarino. After a week-long standoff, a battle began which resulted in the destruction of the OttomanEgyptian fleet. A French expeditionary force was dispatched to supervise the evacuation of the Egyptian army from the Peloponnese, while the Greeks proceeded to the captured part of Central Greece by 1828. As a result of years of negotiation, the nascent Greek state was finally recognized under the London Protocol in 1830." Answer:

Question: "Which hotel existed first?" Context: "The Traymore Hotel was located at the corner of Illinois Avenue and the boardwalk. Begun in 1879 as a small boarding house, the hotel grew through a series of uncoordinated expansions.

The hotel made use of ocean-facing hotel rooms by jutting its wings farther from the main portion of the hotel along Pacific Avenue." Answer:
Ans: the Marlborough-Blenheim

Question: "What was the basis of algebra?" Context: "Three Han mathematical treatises still exist. These are the Book on Numbers and Computation, the Arithmetical Classic of the Gnomon and the Circular Paths of Heaven and the Nine Chapters on the Mathematical Art. Han-era mathematical achievements include solving problems with right-angle triangles, square roots, cube roots, and matrix methods, finding more accurate approximations for pi, providing mathematical proof of the Pythagorean theorem, use of the decimal fraction, Gaussian elimination to solve linear equations, and continued fractions to find the roots of equations." Answer:
Ans: Gaussian elimination to solve linear equations
