Listen to what a group of tourists shopping at an open-air market say? and select the english equivalents of demonstrative adjectives you hear?

Your question is incomplete because it does not provide the recording to listen to. However, the audio tapescript of the recording is the following:

1. Cuánto cuesta este cinturón?

2. Quiero aquel sombrero.

3. Estas sandalias son baratas, ¿verdad?

4. Qué piensas de esa chaqueta?

Explanation:

Demonstrative adjectives this, that, these and those are used to indicate pronouns and nouns.

Thus, this and that are used with singular nouns or pronouns, the first displaying closeness and the second certain remoteness. The Spanish equivalents for this are este (for masculine nouns and pronouns) and esta (for feminine ones). Similarly, the Spanish translations for that are ese or aquel (masculine) and esa and aquella (feminine).

On the othe hand, in the plural, the Spanish for these, indicating proximity, is estos (masculine) and estas (feminine). Meanwhile, those, which expresses distance, can be translated as esos or aquellos (masculine), and esas or aquellas (feminine).
