Problem: In the first year, 400 beer houses opened and within eight years there were 46,000 across the country, far outnumbering the combined total of long-established taverns, pubs, inns and hotels. Because it was so easy to obtain permission and the profits could be huge compared to the low cost of gaining permission, the number of beer houses was continuing to rise and in some towns nearly every other house in a street could be a beer house. Finally in 1869 the growth had to be checked by magisterial control and new licensing laws were introduced. Only then was it made harder to get a licence, and the licensing laws which operate today were formulated.
In what year were additional licensing laws introduced for beer houses?
The answer is the following: 1869

Problem: Guinea-Bissau is bordered by Senegal to the north and Guinea to the south and east, with the Atlantic Ocean to its west. It lies mostly between latitudes 11° and 13°N (a small area is south of 11°), and longitudes 13° and 17°W.
What country is on the south border of Guinea-Bissau?
The answer is the following: Guinea

Problem: Classification seeks to describe the diversity of bacterial species by naming and grouping organisms based on similarities. Bacteria can be classified on the basis of cell structure, cellular metabolism or on differences in cell components, such as DNA, fatty acids, pigments, antigens and quinones. While these schemes allowed the identification and classification of bacterial strains, it was unclear whether these differences represented variation between distinct species or between strains of the same species. This uncertainty was due to the lack of distinctive structures in most bacteria, as well as lateral gene transfer between unrelated species. Due to lateral gene transfer, some closely related bacteria can have very different morphologies and metabolisms. To overcome this uncertainty, modern bacterial classification emphasizes molecular systematics, using genetic techniques such as guanine cytosine ratio determination, genome-genome hybridization, as well as sequencing genes that have not undergone extensive lateral gene transfer, such as the rRNA gene. Classification of bacteria is determined by publication in the International Journal of Systematic Bacteriology, and Bergey's Manual of Systematic Bacteriology. The International Committee on Systematic Bacteriology (ICSB) maintains international rules for the naming of bacteria and taxonomic categories and for the ranking of them in the International Code of Nomenclature of Bacteria.
Can classification be helpful in determining differences between distinct species?
The answer is the following: unclear

Problem: The authors of the study also examined 77 college textbooks in biology and 69 in physical anthropology published between 1932 and 1989. Physical anthropology texts argued that biological races exist until the 1970s, when they began to argue that races do not exist. In contrast, biology textbooks did not undergo such a reversal but many instead dropped their discussion of race altogether. The authors attributed this to biologists trying to avoid discussing the political implications of racial classifications, instead of discussing them, and to the ongoing discussions in biology about the validity of the concept "subspecies". The authors also noted that some widely used textbooks in biology such as Douglas J. Futuyama's 1986 "Evolutionary Biology" had abandoned the race concept, "The concept of race, masking the overwhelming genetic similarity of all peoples and the mosaic patterns of variation that do not correspond to racial divisions, is not only socially dysfunctional but is biologically indefensible as well (pp. 5 18-5 19)." (Lieberman et al. 1992, pp. 316–17)
What were biologists trying to avoid discussing the political implications of?
The answer is the following:
racial classifications
