Answer:
Sus atractivos y exuberantes escenarios naturales son un auténtico paraíso para los científicos.
Explanation:
In this exercise you have to complete the blanks with the correct word.
Statement number one says "Costa Rica is located in a privileged area of the planet. Its attractive places are an authentic paradise<u> for scientists</u>".
Scientists are really interested in Costa Rica because It has so many tropical places and many biology students travel to Costa Rica to work in the natural fields. There is also an organization called "The Organization for Tropical Studies" in which is known and recognized as an academic institution for biological studies.
So the missing word is <em>"scientists".</em>
Yo trabajo el trabaja tú trabajas ellos trabajan and nosotros trabajamos
The possible forms of comparison would be:
1) Carla <u>es más alta que </u>Cristina. (Carla is taller than Cristina.)
This type of comparison follows the next order:
verb <em>ser</em> + <em>más </em>+ adjective + <em>que.</em>
2) If we want to be precise, we could add the exact information and say:
Carla es<u> 5 centímetros </u>más alta que Cristina.
3) We could also say that 'Cristina is shorter than Carla.'
Cristina es más baja que Carla.
We use the same construction, but we just change the adjective <em>alta</em> (tall) for <em>baja</em> (short).
4) And finally, in Spanish, we can say that 'Cristina is <em>less tall</em> than Carla.'
Cristina es menos alta que Carla.
In this case, we just apply the adverb <em>menos</em> meaning <em>less.</em>
