Detail and Specific Information Practice Test

Read the passage and answer the question.

A linguist analyzing changes in coastal dialects compiled a corpus of recorded interviews from the town of Greyhaven. The corpus consisted of 96 interviews: 48 recorded in 1975 and 48 recorded in 2015. Each interview lasted exactly 30 minutes, and all speakers were lifelong residents of Greyhaven. The linguist focused on the pronunciation of the vowel in words like “boat” and coded each instance as either a “raised” or “non-raised” variant. In the 1975 recordings, 31% of coded instances were raised; in the 2015 recordings, 54% were raised. The study explicitly noted that the 2015 speakers had a higher average level of formal education than the 1975 speakers, but it did not provide the education averages. The linguist also stated that the interviews were conducted by different fieldworkers in the two years.

A climatology note describes the instrumentation at the Alpine Ridge weather station. The note states that the station is located at an elevation of 2,480 meters and began continuous operation on October 1, 1998. The station measures air temperature at 2 meters above ground and wind speed at 10 meters above ground. Precipitation is recorded with a tipping-bucket gauge that has a resolution of 0.2 millimeters per tip. The note also specifies that data are logged at 10-minute intervals and transmitted via satellite once per day at 02:00 local time. As a maintenance detail, the note reports that the temperature sensor is calibrated twice per year: in April and in October.
