This is another example of correct use of vocabulary depending on context and knowledge of the topic. Thus, the answers and their explanations, would be as follows:

1. Innovar es un concurso argentino para: inventores (inventors). Innovar is a contest in Argentina for innovators.

2. El chileno Raúl Ramírez inventó una máquina para construir: muros (walls). This guy invented the machine CINVA-RAM, which allowed people from poor households to put on their walls with little cost.

3. La argentina Cecilia Bouzat investigó sobre: Las neuronas (neurons). She was born in 1961 and has been awarded several times for her studies in neurosciences. She was born in Bahía Blanca, Argentina.

4. Ellen Ochoa es: Astronauta e inventora (astronaut and inventor). She is an Hispanic-American woman who became an astronaut and also an engineer. She was born in Los Angeles from Hispanic parents.

5. Si estás en Colombia y quieres ver animación, dices que quieres ver: caricaturas (cartoons). This would be the best option from the two, because although in Colombia, there is a coloquialism that is "dibujitos", they refer to both cartoons and animated films. Since the question is related to animated features, then the best option is cartoons (caricaturas)
