En la parte 3 te dan una palabra al margen y tienes que transformarla para que encaje en el hueco. En C1 casi nunca basta con añadir un sufijo: muchas veces hay que cambiar la categoría y añadir un prefijo negativo.

Lo que hay que comprobar siempre

ComprobaciónEjemplo
¿Qué categoría pide el hueco?Detrás de a sign of va un sustantivo: efficiency, no efficient.
¿Va en singular o plural?Si delante hay many o several, el sustantivo va en plural.
¿Hace falta un prefijo negativo?Si la frase lleva but, although o however, sospecha de un-, in-, dis- o mis-.
¿Hay doble cambio?able puede acabar en unbelievably: prefijo, sufijo de adjetivo y sufijo de adverbio.

Escribe siempre la palabra completa, no solo la parte que cambias. Y revisa la ortografía: en esta parte una letra mal puesta anula el punto.

Ejercicio 1 · Transforma la palabra

Reading the weather without instruments

Long before satellites, sailors and farmers made (1) about the weather by watching the sky, the sea and the behaviour of animals. Modern meteorologists tend to be (2) about these traditions, and often rightly so, but a few of them turn out to be surprisingly (3) .
