Problem: Digestive systems take many forms. There is a fundamental distinction between internal and external digestion. External digestion developed earlier in evolutionary history, and most fungi still rely on it. In this process, enzymes are secreted into the environment surrounding the organism, where they break down an organic material, and some of the products diffuse back to the organism. Animals have a tube (gastrointestinal tract) in which internal digestion occurs, which is more efficient because more of the broken down products can be captured, and the internal chemical environment can be more efficiently controlled.
Why is internal digection better than external?
The answer is the following: more of the broken down products can be captured, and the internal chemical environment can be more efficiently controlled

Problem: The Republic of Cyprus has de jure sovereignty over the island of Cyprus and its surrounding waters, according to international law, except for the British Overseas Territory of Akrotiri and Dhekelia, administered as Sovereign Base Areas. However, the Republic of Cyprus is de facto partitioned into two main parts; the area under the effective control of the Republic, comprising about 59% of the island's area, and the north, administered by the self-declared Turkish Republic of Northern Cyprus, which is recognised only by Turkey, covering about 36% of the island's area. The international community considers the northern part of the island as territory of the Republic of Cyprus occupied by Turkish forces. The occupation is viewed as illegal under international law, amounting to illegal occupation of EU territory since Cyprus became a member of the European Union.
What does the international community consider the northern part of Cyprus?
The answer is the following: territory of the Republic of Cyprus occupied by Turkish forces

Problem: The quarter-wave elements imitate a series-resonant electrical element due to the standing wave present along the conductor. At the resonant frequency, the standing wave has a current peak and voltage node (minimum) at the feed. In electrical terms, this means the element has minimum reactance, generating the maximum current for minimum voltage. This is the ideal situation, because it produces the maximum output for the minimum input, producing the highest possible efficiency. Contrary to an ideal (lossless) series-resonant circuit, a finite resistance remains (corresponding to the relatively small voltage at the feed-point) due to the antenna's radiation resistance as well as any actual electrical losses.
How would you describe a current that has maximum efficiency?
The answer is the following: minimum reactance

Problem: Numerous men from Detroit volunteered to fight for the Union during the American Civil War, including the 24th Michigan Infantry Regiment (part of the legendary Iron Brigade), which fought with distinction and suffered 82% casualties at the Battle of Gettysburg in 1863. When the First Volunteer Infantry Regiment arrived to fortify Washington, DC, President Abraham Lincoln is quoted as saying "Thank God for Michigan!" George Armstrong Custer led the Michigan Brigade during the Civil War and called them the "Wolverines".
What Brigade was the 24th Michigan Infantry Regiment a part of?
The answer is the following:
Iron Brigade
