Problem: Fortaleza del Cerro overlooks the bay of Montevideo. An observation post at this location was first built by the Spanish in the late 18th century. In 1802, a beacon replaced the observation post; construction of the fortress began in 1809 and was completed in 1839. It has been involved in many historical developments and has been repeatedly taken over by various sides. In 1907, the old beacon was replaced with a stronger electric one. It has been a National Monument since 1931 and has housed a military museum since 1916. Today it is one of the tourist attractions of Montevideo.
What replaced the observation post in 1802?
The answer is the following: a beacon

Problem: The Arthur Ravenel Jr. Bridge across the Cooper River opened on July 16, 2005, and was the second-longest cable-stayed bridge in the Americas at the time of its construction.[citation needed] The bridge links Mount Pleasant with downtown Charleston, and has eight lanes plus a 12-foot lane shared by pedestrians and bicycles. It replaced the Grace Memorial Bridge (built in 1929) and the Silas N. Pearman Bridge (built in 1966). They were considered two of the more dangerous bridges in America and were demolished after the Ravenel Bridge opened.
What is linked to downtown Charleston by the bridge?
The answer is the following: Mount Pleasant

Problem: On 23 February, the 28th Marine Regiment reached the summit of Suribachi, prompting the now famous Raising the Flag on Iwo Jima picture. Navy Secretary James Forrestal, upon seeing the flag, remarked "there will be a Marine Corps for the next 500 years." The flag raising is often cited as the most reproduced photograph of all time and became the archetypal representation not only of that battle, but of the entire Pacific War. For the rest of February, the Americans pushed north, and by 1 March, had taken two-thirds of the island. But it was not until 26 March that the island was finally secured. The Japanese fought to the last man, killing 6,800 Marines and wounding nearly 20,000 more. The Japanese losses totaled well over 20,000 men killed, and only 1,083 prisoners were taken. Historians debate whether it was strategically worth the casualties sustained.
Who said "there will be a Marine Corps for the next 500 years"?
The answer is the following: Navy Secretary James Forrestal

Problem: Though Jehovah's Witnesses do not accept blood transfusions of whole blood, they may accept some blood plasma fractions at their own discretion.
