Question

1. ★ image of two spiral-bound notebooks (one yellow, one blue)

el cuaderno
un cuaderno

Explanation:

The image shows two notebooks (cuadernos). "El cuaderno" is the definite article form (the notebook) and "un cuaderno" is the indefinite article form (a notebook). If the question is about identifying the correct article or the noun, the noun here is "cuaderno" (notebook), and the articles are "el" (definite, masculine singular) and "un" (indefinite, masculine singular) since "cuaderno" is a masculine noun in Spanish.

Answer:

The noun is "cuaderno" (meaning "notebook" in Spanish). The articles are "el" (definite, "the") and "un" (indefinite, "a"). If the task is to identify the correct way to refer to the notebook(s) shown, for the yellow notebook (the one in front), we can say "el cuaderno" (the notebook), and for a notebook in general or either of them, "un cuaderno" (a notebook).
