The annual rainfall in a city over the past 50 years is its historical average rainfall (HAR). The graph above shows the annual rainfall in City X over a seven-year period. All figures are rounded to the nearest integer.

Is it true that the rounded historical average rainfall (HAR) for City X over the past 50 years is 47 mm or greater?

（1） In the seven-year period in City X, the annual rainfall was greater than the HAR in exactly two of the consecutive years.

（2）In the seven-year period in City X, the annual rainfall was less than the HAR in exactly four of the years.

Although Victor Turner’s writings have proved fruitful for fields beyond anthropology, his definition of ritual is overly restrictive. Ritual, he says, is “prescribed formal behavior for occasions not given over to technological routine, having reference to beliefs in mystical beings or powers.” “Technological routine” refers to the means by which a social group provides for its material needs. Turner’s differentiating ritual from technology helps us recognize that festivals and celebrations may have little purpose other than play, but it obscures the practical aims, such as making crops grow or healing patients, of other rituals. Further, Turner’s definition implies a necessary relationship between ritual and mystical beliefs. However, not all rituals are religious; some religions have no reference to mystical beings; and individuals may be required only to participate in, not necessarily believe in, a ritual. Turner’s assumption that ritual behavior follows belief thus limits the usefulness of his definition in studying ritual across cultures.
