The correct sentence that can be formed with the words given is:
- Ángel <u>abre</u> la puerta <u>del</u> laboratorio.
- Mi cuñada y yo <u>decidimos</u> leer libros interesantes.

Explanation:
The translation of the sentences is:

Taking into account the words provided, two things were really required to create appropriate sentences:
- <u>Know the correct conjugation in Present Simple of the verbs used.
</u>
- <u>Know some connectors to give readability to the sentence</u>.
To solve the first point below is the appropriate conjugation of the verbs used in Simple Present:
Yo abro/decido/asisto.
Tú abres/decides/<u>asistes</u>.
Usted abre/decide/asiste.
Él <u>abre</u>/decide/asiste.
Ella abre/decide/asiste.
Ello abre/decide/asiste.
Nosotros abrimos/<u>decidimos</u>/asistimos.
Ustedes abren/deciden/asisten.
Ellos abren/deciden/asisten.
For the second part, remember that you can use connectors like <em>de, del, para, con</em> or some defined articles as <em>el, la, los</em> and <em>las</em>.
