Answer:
The right writing of the adjectives in each case is:
<em>-</em><em> Mi madre es muy </em><u><em>trabajadora</em></u><em>: es artista y también enseña en una universidad. A los estudiantes les gusta mi madre porque es una profesora </em><u><em>buena</em></u><em>, pero ella da exámenes muy </em><u><em>difíciles</em></u><em>. Este semestre enseña dos clases de arte.</em>
Explanation:
The translation of the paragraph is:
- My mother is a <u>hard worker</u>: she is an artist and also teaches at a university. The students like my mother because she is a <u>good</u> teacher, but she gives very <u>difficult</u> exams. This semester teaches two art classes.
Although in English the adjectives are always singular and do not undergo changes regardless of the gender of the noun, in Spanish both the gender and the number of the noun must be taken into account in order to use the same adjective form, to identify whether the adjective used is correct or not first you must verify to what gender and number each one belongs:
- <em>Trabajadora:</em> singular and female.
- <em>Buena: </em>singular and female.
- <em>Difíciles:</em> plural and male/female.
As the first and second referred to the mother, singular adjectives are used and whose gender is female or both, meanwhile the third adjective is used for a plural and male noun <u><em>"exámenes"</em></u>.
