Write a paragraph, in Spanish, about natural and agricultural resources in Costa Rica and what will happen if these resources are not conserved.

Llena el espacio con la forma del verbo que se escribe correctamente. ¿quién estas tortillas ricas?

Okay so i'm taking an online spanish course (penn foster), and in the study guide, you have to create a bunch of sentences with words you've learned so far. translating, reading, and those kinds of things are fairly easy, but when it comes to making my own sentences, my brain just kinda waltz's away. anyone got any tips?

Write the indefinite article ( un, una, unos, unas ) for each word. if both masculine and feminine articles are possible, write both. 1. autobús 2. foto (fotografía) 3. turistas 4. números
