A short exercise, **we only have to join the definitions with the words**, for them we must know what each of these mean.

| cohete |rocket |
|buscador | search engine |
| telescopio| telescope |
|clonar | clone |
| arroba | at |
|ovni | UFO |

Finally we just need to *associate each meanig with the corresponding word:*

1. Se utiliza en la direcciones de correo electrónico: **arroba**.
2. Un objeto extraterrestre: **ovni**.
3. Reproducir un ser vivo exactamente igual: **clonar**.
4. Se utiliza para investigar en internet: **buscador**.
5. El vehículo que se utiliza para ir al espacio: **cohete**.
6. Se utiliza para ver las estrellas: **telescopio**.

For this you need to identifies the word that does not belong to the group.

As other exercises, we will translate everything for a better understanding:

|ADN-célula- buscador – gen | DNA-cell – search engine – gene |
|astronauta-red-cohete-espacio | astronaut-network-rocket-space|
| descargar-adjuntar-guardar- clonar |download-attach-save-clone |
| descubrimiento-gravedad – avance-invento | discovery-gravity – breakthrough-invention |
| bioquímico-avanza do-revolucionario-in novador | biochemist-advance-revolutionary-innovator |
| cientffico-biólogo-extraterrestre-ingeniero | scientist-biologist alieb-engineer |

1. Now for the first group, we can see that we are talking about biology, so the word that is left is **buscador/search engine**.

2. The topic in this group is space stuff, so we can say that the word we are looking for is **red/network**.

3. Now we can see that we are only talking about functions in a computer, so the word that is left over is **clonar/clone**.

4. When we talk about actions, our word is **gravedad/gravity**.

5. On the subject of net progress, the sciences are not part of the discussion. So **bioquímico/biochemist** is left over.

6. In the last group, we talk about careers, our leftover word is **extraterrestre/alien**.
