Answer:
The logical sentences that could make with the words in parentheses are:
1. En el desierto hay <u>más</u> cactus <u>que</u> ríos.
2. En el cielo hay <u>más</u> estrellas <u>que</u> peces en el océano.
3. Hay <u>más </u>libros <u>que</u> lectores en el mundo.
Explanation:
Taking into account just the words in parentheses <em>(más-que)</em> that could be translated by <u>(more-than)</u> or the adjective finished in <u>'er'-than</u>, I have written three sentences that apply to the comparative form using first the words separated by slashes, and next <u>I made other sentences that could be written with the words given following the same style</u>, then, the translation of the sentences is:
1. In the desert, there are <u>more </u>cactus <u>than</u> rivers.
2. In the sky, there are <u>more</u> stars <u>than</u> fish in the ocean.
3. There are <u>more</u> books <u>than</u> readers in the world.
