Question

confuses the predator and keeps its attention, so the octopus has time to get away safely.
lizards are even more unusual. they can disconnect their tails from their bodies when a predator threatens them.
their tails are built with spaces between the bones where they can break off. it takes a lot of time and energy for a lizard to grow its tail back, but its better than being eaten.
breaking off a tail is easy, but regrowing it takes time.
why would a lizard need to disconnect its tail?
to become stronger
to frighten predator
to grow new bones
to avoid being eaten

Explanation:

El texto explica que los lagartos desconectan la cola para escapar de depredadores, y la opción "to avoid being eaten" coincide con esta finalidad (evitar ser comidos). Las otras opciones no se apoyan en el texto: "to grow new bones" no es el propósito principal, "to frighten predator" no se menciona que la cola asuste, y "to become stronger" tampoco está relacionado.

Answer:

to avoid being eaten (la opción correspondiente, por ejemplo, si es la primera tarjeta: "to avoid being eaten")
