An English language textbook, open to Unit 13 on the Past Continuous tense, rests on a person's lap, visible as light grey denim fabric. The left page illustrates the tense with drawings of a person swimming and another watching television, a timeline indicating "he started swimming" at 3:30, "he was swimming" at 4:00, and "he finished swimming" at 4:15, along with grammatical tables for positive, negative, and question forms. The right page displays "Exercises 13.1," featuring pictures of people in various settings and partially completed handwritten answers in blue ink, such as "Rachel was at home watch TV." A faint shadow covers the lower right portion of the right page. A reddish surface, possibly part of a chair or table, is visible in the upper left background. The immediate environment is an indoor setting. The image provides no discernible information regarding its specific location within the city of Yerevan, Armenia.
