Problem: Hunting big game typically requires a "tag" for each animal harvested. Tags must be purchased in addition to the hunting license, and the number of tags issued to an individual is typically limited. In cases where there are more prospective hunters than the quota for that species, tags are usually assigned by lottery. Tags may be further restricted to a specific area, or wildlife management unit. Hunting migratory waterfowl requires a duck stamp from the Fish and Wildlife Service in addition to the appropriate state hunting license.
What is typically limited to an individual?
The answer is the following: number of tags issued

Problem: Uncompressed audio as stored on an audio-CD has a bit rate of 1,411.2 kbit/s, (16 bit/sample × 44100 samples/second × 2 channels / 1000 bits/kilobit), so the bitrates 128, 160 and 192 kbit/s represent compression ratios of approximately 11:1, 9:1 and 7:1 respectively.
What would a bit rate of 192 kbit/s have for a compression ratio?
The answer is the following: 7:1

Problem: In Brazil, the fall of the monarchy in 1889 by a military coup d'état led to the rise of the presidential system, headed by Deodoro da Fonseca. Aided by well-known jurist Ruy Barbosa, Fonseca established federalism in Brazil by decree, but this system of government would be confirmed by every Brazilian constitution since 1891, although some of them would distort some of the federalist principles. The 1937 Constitution, for example, granted the federal government the authority to appoint State Governors (called interventors) at will, thus centralizing power in the hands of President Getúlio Vargas. Brazil also uses the Fonseca system to regulate interstate trade. Brazil is one of the biggest federal governments.
Who caused the fall of the monarchy happened in Brazil?
The answer is the following: military coup d'état led to the rise of the presidential system, headed by Deodoro da Fonseca.

Problem: Gram-positive bacteria possess a thick cell wall containing many layers of peptidoglycan and teichoic acids. In contrast, gram-negative bacteria have a relatively thin cell wall consisting of a few layers of peptidoglycan surrounded by a second lipid membrane containing lipopolysaccharides and lipoproteins. Lipopolysaccharides, also called endotoxins, are composed of polysaccharides and lipid A that is responsible for much of the toxicity of gram-negative bacteria. Most bacteria have the gram-negative cell wall, and only the Firmicutes and Actinobacteria have the alternative gram-positive arrangement. These two groups were previously known as the low G+C and high G+C Gram-positive bacteria, respectively. These differences in structure can produce differences in antibiotic susceptibility; for instance, vancomycin can kill only gram-positive bacteria and is ineffective against gram-negative pathogens, such as Haemophilus influenzae or Pseudomonas aeruginosa. If the bacterial cell wall is entirely removed, it is called a protoplast, whereas if it is partially removed, it is called a spheroplast. β-Lactam antibiotics, such as penicillin, inhibit the formation of peptidoglycan cross-links in the bacterial cell wall. The enzyme lysozyme, found in human tears, also digests the cell wall of bacteria and is the body's main defense against eye infections.
What can different structure of the cell walls of bacteria effect?
The answer is the following:
differences in antibiotic susceptibility
