Problem: President Abraham Lincoln visited General Grant at Petersburg on April 3, and took a launch to Richmond the next day, while Jefferson Davis attempted to organize his Confederate government at Danville. Lincoln met Confederate assistant secretary of War John A. Campbell, and handed him a note inviting Virginia's legislature to end their rebellion. After Campbell spun the note to Confederate legislators as a possible end to the Emancipation Proclamation, Lincoln rescinded his offer and ordered General Weitzel to prevent the Confederate state legislature from meeting. Union forces killed, wounded or captured 8000 Confederate troops at Saylor's Creek southwest of Petersburg on April 6. General Lee continued to reject General Grant's surrender suggestion until Sheridan's infantry and cavalry appeared in front of his retreating army on April 8. He surrendered his remaining approximately 10000 troops at Appomattox Court House the following morning. Jefferson Davis retreated to North Carolina, then further south. when Lincoln rejected the surrender terms negotiated by general Sherman and envoys of North Carolina governor Zebulon Vance, which failed to mention slavery. Davis was captured on May 10 near Irwinville, Georgia and taken back to Virginia, where he was charged with treason and imprisoned for two years at Fort Monroe until freed on bail.
In what structure did Lee surrender to Grant?
The answer is the following: Appomattox Court House

Problem: The development of the appreciation medals was initiated by the White House and executed by the Bureau of the Mint through the U.S. Mint in Philadelphia. The medals were struck from September 1958 through October 1960. A total of twenty designs are cataloged with a total mintage of 9,858. Each of the designs incorporates the text "with appreciation" or "with personal and official gratitude" accompanied with Eisenhower's initials "D.D.E." or facsimile signature. The design also incorporates location, date, and/or significant event. Prior to the end of his second term as President, 1,451 medals were turned-in to the Bureau of the Mint and destroyed. The Eisenhower appreciation medals are part of the Presidential Medal of Appreciation Award Medal Series.
How many appreciation medals were minted?
The answer is the following: 9,858

Problem: Schwarzenegger met his next paramour, Sue Moray, a Beverly Hills hairdresser's assistant, on Venice Beach in July 1977. According to Moray, the couple led an open relationship: "We were faithful when we were both in LA … but when he was out of town, we were free to do whatever we wanted." Schwarzenegger met Maria Shriver at the Robert F. Kennedy Tennis Tournament in August 1977, and went on to have a relationship with both women until August 1978, when Moray (who knew of his relationship with Shriver) issued an ultimatum.
What was the name of the hairdresser's assistant Schwarzenegger fell for in July of 1977?
The answer is the following: Sue Moray

Problem: Insects were the earliest organisms to produce and sense sounds. Insects make sounds mostly by mechanical action of appendages. In grasshoppers and crickets, this is achieved by stridulation. Cicadas make the loudest sounds among the insects by producing and amplifying sounds with special modifications to their body and musculature. The African cicada Brevisana brevis has been measured at 106.7 decibels at a distance of 50 cm (20 in). Some insects, such as the Helicoverpa zeamoths, hawk moths and Hedylid butterflies, can hear ultrasound and take evasive action when they sense that they have been detected by bats. Some moths produce ultrasonic clicks that were once thought to have a role in jamming bat echolocation. The ultrasonic clicks were subsequently found to be produced mostly by unpalatable moths to warn bats, just as warning colorations are used against predators that hunt by sight. Some otherwise palatable moths have evolved to mimic these calls. More recently, the claim that some moths can jam bat sonar has been revisited. Ultrasonic recording and high-speed infrared videography of bat-moth interactions suggest the palatable tiger moth really does defend against attacking big brown bats using ultrasonic clicks that jam bat sonar.
What were the earliest organisms to produce sound?
The answer is the following:
Insects
