Article: Plants and various other groups of photosynthetic eukaryotes collectively known as "algae" have unique organelles known as chloroplasts. Chloroplasts are thought to be descended from cyanobacteria that formed endosymbiotic relationships with ancient plant and algal ancestors. Chloroplasts and cyanobacteria contain the blue-green pigment chlorophyll a. Chlorophyll a (as well as its plant and green algal-specific cousin chlorophyll b)[a] absorbs light in the blue-violet and orange/red parts of the spectrum while reflecting and transmitting the green light that we see as the characteristic colour of these organisms. The energy in the red and blue light that these pigments absorb is used by chloroplasts to make energy-rich carbon compounds from carbon dioxide and water by oxygenic photosynthesis, a process that generates molecular oxygen (O2) as a by-product.

Question: What color does a plant with chlorophyll appear to be?
Ans: green

US troops participated in a UN peacekeeping mission in Somalia beginning in 1992. By 1993 the US troops were augmented with Rangers and special forces with the aim of capturing warlord Mohamed Farrah Aidid, whose forces had massacred peacekeepers from Pakistan. During a raid in downtown Mogadishu, US troops became trapped overnight by a general uprising in the Battle of Mogadishu. Eighteen American soldiers were killed, and a US television crew filmed graphic images of the body of one soldier being dragged through the streets by an angry mob. Somali guerrillas paid a staggering toll at an estimated 1,000–5,000 total casualties during the conflict. After much public disapproval, American forces were quickly withdrawn by President Bill Clinton. The incident profoundly affected US thinking about peacekeeping and intervention. The book Black Hawk Down was written about the battle, and was the basis for the later movie of the same name.

How many US soldiers were killed in the battle of Mogadishu?
Answer: Eighteen


The Ricketts family acquired a majority interest in the Cubs in 2009, ending the Tribune years. Apparently handcuffed by the Tribune's bankruptcy and the sale of the club to the Ricketts family, the Cubs' quest for a NL Central 3-peat started with notice that there would be less invested into contracts than in previous years. Chicago engaged St. Louis in a see-saw battle for first place into August 2009, but the Cardinals played to a torrid 20–6 pace that month, designating their rivals to battle in the Wild Card race, from which they were eliminated in the season's final week. The Cubs were plagued by injuries in 2009, and were only able to field their Opening Day starting lineup three times the entire season. Third baseman Aramis Ramírez injured his throwing shoulder in an early May game against the Milwaukee Brewers, sidelining him until early July and forcing journeyman players like Mike Fontenot and Aaron Miles into more prominent roles. Additionally, key players like Derrek Lee (who still managed to hit .306 with 35 HR and 111 RBI that season), Alfonso Soriano and Geovany Soto also nursed nagging injuries. The Cubs posted a winning record (83–78) for the third consecutive season, the first time the club had done so since 1972, and a new era of ownership under the Ricketts' family was approved by MLB owners in early October.
Who did Chicago engage in a see-saw battle for first place into August 2009?
St. Louis
