During an English class, a teacher introduced the concept of compound nouns, explaining that they are words formed by combining two words from the same or different grammatical classes. To illustrate the explanation that was offered, an advertisement was projected on the screen, and the students identified a compound noun. The teacher clarified that the word in question is formed by two words belonging to the same word class. Next, the teacher provided a list of words and asked the students to identify those that share the same compound structure as the word previously analyzed.
Select the alternative which contains the compound nouns students should spot.
