Answer 1.
Me gusta el carro que esta lejos. Me gusta ese
This lesson stands for demonstrative adjectives, such as este, ese and aquel. So these adjectives demonstrate a quality about the noun they modify. Here that quality is the location in respect to the speaker or the listener. Here we use ese because the word carro (car) is a masculine and singular noun and ese matches this type of nouns. So ese indicates something more distant, that is, nouns that are further from the speaker but they can be close to the listener.
Answer 2.
Me gustan las computadoras que estan cerca de mi. Me gustan estas
Here we choose estas because it indicates something near to the speaker in space. Since we are talking about computers (computadoras), we are talking in plural form, therefore the form este changes to feminine and plural form as estas, that is, I am talking about these computers (estas computadoras) that are near me.
Answer 3.
A mi padre le gustan las Islas muy lejos de nuestra casa. Le gustan aquellas
Here we choose aquellas because indicates something that is far away from both the speaker and the listener. Since islas is a feminine and plural noun, we need to use the demonstrative adjectives for it matches feminine and plural nouns. Therefore, my father likes islands that are far away from here.
