Explanation:

In order to make the sentences we have to use the present tense of the verb 'estar' (to be):

Estar:

Yo estoy

Tu estás

El/ ella está

Nosotros estamos

Ustedes están

Ellos/Ellas están

We indentify de subject of each sentence and we choose the right tense of the verb:

Question 1: 'Casa' is a singular female noun, we have to use the article 'La' and choose 'está' as the right verb tense. 'Parque' is a singular male noun so we have to use 'del' as a contraction. La casa está lejos del parque.

Question 2: 'Libros' is a plural male noun, we have to use the article 'Los' and choose 'están' as the right verb tense. 'Escritorio' is a singular male noun so we have to use 'del' as a contraction. Los libros están cerca del escritorio.

Question 3: The right tense for 'Ustedes' is 'están'. 'Puerta' is a singular female noun so we have to use 'de la' as a contraction. Ustedes están al lado de la puerta.

Question 4: 'Calculadora' is a singular female noun, we have to use the article 'La' and choose 'está' as the right verb tense. 'Computadoras' is a plural female noun so we have to use 'las' as an article. La calculadora está entre las computadoras.

Question 5: 'Lápices' is a plural male noun, we have to use the article 'Los' and choose 'están' as the right verb tense. 'Cuaderno' is a singular male noun so we have to use 'el' as an article. Los lápices están sobre el cuaderno.

Question 6: 'Estadio' is a singular male noun, we have to use the article 'El' and choose 'está' as the right verb tense. 'Resicencias' is a plural female noun so we have to use 'de las' as a contraction. El estadio está lejos de las residencias.

Question 7: 'Mochilas' is a plural female noun, we have to use the article 'Las' and choose 'están' as the right verb tense. 'Mesa' is a singular female noun so we have to use 'de la' as a contraction. Las mochilas están debajo de la mesa.

Question 8: The right verb tense for 'Tú' is 'estás'. 'Clase' is a singular female noun so we have to use 'la' as an article. Tú estás en la clase de psicología.
