I'm confused on what the directions tell me, and what I'm supposed to do. The excersise says:

Hay personas que hacen muchas cosas. Hay otras que no hacen nada. Exprese eso en oraciones negativas.

I know part of it says...

There are people who do many things. There are other people who don't do anything.

Then what does it say after that?

Then...
1. Clara hizo interesante ayer.
Yo_____________________________

2. Felipe encontro a alguien simpatico en la fiesta.
Tu_________________________________
3. Alguien invita a Pilar a cenar en un restaurante japones.
____________a Carmen _____________

1. Yo no hice nada interesante ayer.

2. Tu no encontraste a nadie simpatico en la fiesta.

The exercise is asking you to express the given sentences in negative form. Let's break down the sentences to understand what is being said and how to make them negative.

Sentence 1:
Clara hizo interesante ayer.
Translation: Clara did something interesting yesterday.

To make it negative, you need to express that Clara did not do anything interesting. In Spanish, you can use the word "nada" to mean "nothing." So, the negative sentence would be:
Yo no hice nada interesante ayer.
Translation: I didn't do anything interesting yesterday.

Sentence 2:
Felipe encontro a alguien simpatico en la fiesta.
Translation: Felipe met someone nice at the party.

To make it negative, you need to express that Felipe did not meet anyone nice. In Spanish, you can use the word "nadie" to mean "no one." So, the negative sentence would be:
Tu no encontraste a nadie simpatico en la fiesta.
Translation: You didn't meet anyone nice at the party.

Sentence 3:
Alguien invita a Pilar a cenar en un restaurante japones.
Translation: Someone invites Pilar to have dinner at a Japanese restaurant.

To make it negative, you need to express that no one invites Pilar to have dinner. In Spanish, you can use the phrase "nadie invita" to mean "nobody invites." So, the negative sentence would be:
Nadie invita a Carmen a cenar en un restaurante japones.
Translation: Nobody invites Carmen to have dinner at a Japanese restaurant.

In summary, the negative sentences would be:
1. Yo no hice nada interesante ayer. (I didn't do anything interesting yesterday.)
2. Tu no encontraste a nadie simpatico en la fiesta. (You didn't meet anyone nice at the party.)
3. Nadie invita a Carmen a cenar en un restaurante japones. (Nobody invites Carmen to have dinner at a Japanese restaurant.)

Remember, when making negative sentences in Spanish, you usually need to use "no" before the verb and sometimes add words like "nada" or "nadie" to express "nothing" or "no one."
