QUES: With Eisenhower's leadership and Dulles' direction, CIA activities increased under the pretense of resisting the spread of communism in poorer countries; the CIA in part deposed the leaders of Iran in Operation Ajax, of Guatemala through Operation Pbsuccess, and possibly the newly independent Republic of the Congo (Léopoldville). In 1954 Eisenhower wanted to increase surveillance inside the Soviet Union. With Dulles' recommendation, he authorized the deployment of thirty Lockheed U-2's at a cost of $35 million. The Eisenhower administration also planned the Bay of Pigs Invasion to overthrow Fidel Castro in Cuba, which John F. Kennedy was left to carry out."

QUES: Following the '69 season, the club posted winning records for the next few seasons, but no playoff action. After the core players of those teams started to move on, the 70s got worse for the team, and they became known as "The Loveable Losers." In 1977, the team found some life, but ultimately experienced one of its biggest collapses. The Cubs hit a high-water mark on June 28 at 47–22, boasting an 8 1⁄2 game NL East lead, as they were led by Bobby Murcer (27 Hr/89 RBI), and Rick Reuschel (20–10). However, the Philadelphia Phillies cut the lead to two by the All-star break, as the Cubs sat 19 games over .500, but they swooned late in the season, going 20–40 after July 31. The Cubs finished in 4th place at 81–81, while Philadelphia surged, finishing with 101 wins. The following two seasons also saw the Cubs get off to a fast start, as the team rallied to over 10 games above .500 well into both seasons, only to again wear down and play poorly later on, and ultimately settling back to mediocrity. This trait became known as the "June Swoon." Again, the Cubs' unusually high number of day games is often pointed to as one reason for the team's inconsistent late season play.
What is often pointed to as the one reason for the Cubs' inconsistent late season play?

ANS: unusually high number of day games

QUES: The great majority of asphalt used commercially is obtained from petroleum. Nonetheless, large amounts of asphalt occur in concentrated form in nature. Naturally occurring deposits of asphalt/bitumen are formed from the remains of ancient, microscopic algae (diatoms) and other once-living things. These remains were deposited in the mud on the bottom of the ocean or lake where the organisms lived. Under the heat (above 50 °C) and pressure of burial deep in the earth, the remains were transformed into materials such as asphalt/bitumen, kerogen, or petroleum.
From where does most asphalt come?

ANS: petroleum

QUES: With the arrival of Francisco Vázquez de Coronado, a Spanish conquistador, the first recorded history of encounter between Europeans and Native Americans in the Great Plains occurred in Texas, Kansas and Nebraska from 1540-1542. In that same time period, Hernando de Soto crossed a west-northwest direction in what is now Oklahoma and Texas. Today this is known as the De Soto Trail. The Spanish thought the Great Plains were the location of the mythological Quivira and Cíbola, a place said to be rich in gold.
