Problem: Solar energy:

Solar hot water systems use sunlight to heat water. In low geographical latitudes (below 40 degrees) from 60 to 70% of the domestic hot water use with temperatures up to 60 °C can be provided by solar heating systems. The most common types of solar water heaters are evacuated tube collectors (44%) and glazed flat plate collectors (34%) generally used for domestic hot water; and unglazed plastic collectors (21%) used mainly to heat swimming pools.

What is a common type of solar water heater?
---
A: evacuated tube collectors

Problem: Gene:

The duplication and transmission of genetic material from one generation of cells to the next is the basis for molecular inheritance, and the link between the classical and molecular pictures of genes. Organisms inherit the characteristics of their parents because the cells of the offspring contain copies of the genes in their parents' cells. In asexually reproducing organisms, the offspring will be a genetic copy or clone of the parent organism. In sexually reproducing organisms, a specialized form of cell division called meiosis produces cells called gametes or germ cells that are haploid, or contain only one copy of each gene.:20.2 The gametes produced by females are called eggs or ova, and those produced by males are called sperm. Two gametes fuse to form a diploid fertilized egg, a single cell that has two sets of genes, with one copy of each gene from the mother and one from the father.:20

In what type of organism will a specialized form of cell division called meiosis produce cells called gametes?
---
A: In sexually reproducing organisms


Problem: Chicago Cubs:

Before signing a developmental agreement with the Kane County Cougars in 2012, the Cubs had a Class A minor league affiliation on two occasions with the Peoria Chiefs (1985–1995 and 2004–2012). Ryne Sandberg managed the Chiefs from 2006 to 2010. In the period between those associations with the Chiefs the club had affiliations with the Dayton Dragons and Lansing Lugnuts. The Lugnuts were often affectionately referred to by Chip Caray as "Steve Stone's favorite team." The 2007 developmental contract with the Tennessee Smokies was preceded by Double A affiliations with the Orlando Cubs and West Tenn Diamond Jaxx. On September 16, 2014 the Cubs announced a move of their top Class A affiliate from Daytona in the Florida State League to Myrtle Beach in the Carolina League for the 2015 season. Two days later, on the 18th, the Cubs signed a 4-year player development contract with the South Bend Silver Hawks of the Midwest League, ending their brief relationship with the Kane County Cougars and shortly thereafter renaming the Silver Hawks the South Bend Cubs.

When did the Cubs announce a move of their top class A affiliate from Daytona to Myrtle Beach?
