This task is about writing a correct answer for the reading comprehension task. Based on the information provided in a given passage, you should identify the shortest continuous text span from the passage that serves as an answer to the given question. Avoid answers that are incorrect or provides incomplete justification for the question.

Q: Passage: Anthropologists have most frequently employed the term 'identity' to refer to this idea of selfhood in a loosely Eriksonian way (Erikson 1972) properties based on the uniqueness and individuality which makes a person distinct from others. Identity became of more interest to anthropologists with the emergence of modern concerns with ethnicity and social movements in the 1970s. This was reinforced by an appreciation, following the trend in sociological thought, of the manner in which the individual is affected by and contributes to the overall social context. At the same time, the Eriksonian approach to identity remained in force, with the result that identity has continued until recently to be used in a largely socio-historical way to refer to qualities of sameness in relation to a person's connection to others and to a particular group of people. Question: Until recently, what approach was used to refer to qualities of sameness in relation to a person's connection to others?

A: the Eriksonian approach

Q: Passage: Varmint hunting is an American phrase for the selective killing of non-game animals seen as pests. While not always an efficient form of pest control, varmint hunting achieves selective control of pests while providing recreation and is much less regulated. Varmint species are often responsible for detrimental effects on crops, livestock, landscaping, infrastructure, and pets. Some animals, such as wild rabbits or squirrels, may be utilised for fur or meat, but often no use is made of the carcass. Which species are varmints depends on the circumstance and area. Common varmints may include various rodents, coyotes, crows, foxes, feral cats, and feral hogs. Some animals once considered varmints are now protected, such as wolves. In the US state of Louisiana, a non-native rodent known as a nutria has become so destructive to the local ecosystem that the state has initiated a bounty program to help control the population. Question: What has the state of Louisiana done to combat the nutria?

A: initiated a bounty program

Q: Passage: The pitch of complex tones can be ambiguous, meaning that two or more different pitches can be perceived, depending upon the observer. When the actual fundamental frequency can be precisely determined through physical measurement, it may differ from the perceived pitch because of overtones, also known as upper partials, harmonic or otherwise. A complex tone composed of two sine waves of 1000 and 1200 Hz may sometimes be heard as up to three pitches: two spectral pitches at 1000 and 1200 Hz, derived from the physical frequencies of the pure tones, and the combination tone at 200 Hz, corresponding to the repetition rate of the waveform. In a situation like this, the percept at 200 Hz is commonly referred to as the missing fundamental, which is often the greatest common divisor of the frequencies present. Question:  The percept at 200 Hz is commonly referred to as?

A:
the missing fundamental
