Last Saturday, our library held its first repair café. The event was so (0) successful (SUCCESS) that the organisers have already planned another one.

Before the doors opened, a team of Hueco 1VOLUNTEER arranged tables and tools. Each visitor received a short Hueco 2EXPLAIN of the safety rules. We were asked to wait Hueco 3PATIENT, without complaining, while someone checked our broken objects.

At first, I thought my old radio was Hueco 4POSSIBLE to repair: three shops had already told me that nothing could be done. However, a local engineer found a simple Hueco 5SOLVE to the problem and had it working in minutes. She explained each step so Hueco 6CLEAR that everyone could follow her instructions.

By the end of the afternoon, more than twenty objects were ready to use again. Keeping them out of the bin meant a Hueco 7REDUCE in household waste. I also left with a much better Hueco 8UNDERSTAND of how everyday objects work. Next time, I plan to bring a friend and stay for the whole afternoon.

Respuestas y explicaciones

Lee el motivo de cada respuesta, vuelve al texto y encuentra las pistas por tu cuenta.

Pregunta 1: Mostrar respuesta y explicación

Respuesta: volunteers

VOLUNTEER → volunteers.

A team consists of several people, so ‘a team of’ needs the plural noun volunteers here. Add -s to volunteer. Voluntary is an adjective and cannot name the people in this gap.

Pregunta 2: Mostrar respuesta y explicación

Respuesta: explanation

EXPLAIN → explanation.

“Each visitor received a short explanation of the safety rules.” The article a and adjective short introduce a singular noun. Explain is a verb; its noun is explanation, with no i after the a. Simply adding -ation to explain gives the incorrect spelling explaination. Read the whole noun phrase: a short explanation, but an explanation if short is omitted.

Pregunta 3: Mostrar respuesta y explicación

Respuesta: patiently

PATIENT → patiently.

The gap describes how visitors should wait, so it needs an adverb. Add -ly to the adjective patient. ‘Without complaining’ supports patiently, rather than the negative form impatiently.

Pregunta 4: Mostrar respuesta y explicación

Respuesta: impossible

POSSIBLE → impossible.

The shops had said that nothing could be done, so the writer initially believed the radio could not be repaired. The adjective must therefore be negative: impossible. Possible takes the prefix im-, not un- or in-.

Pregunta 5: Mostrar respuesta y explicación

Respuesta: solution

SOLVE → solution.

‘A simple’ needs a singular noun, and the usual phrase is ‘a solution to a problem’. The verb solve changes to the noun solution. Do not use solving after ‘a simple’ in this phrase.

Pregunta 6: Mostrar respuesta y explicación

Respuesta: clearly

CLEAR → clearly.

We need to describe how the engineer explained the steps, so the adjective clear becomes the adverb clearly. The result, ‘everyone could follow her instructions’, confirms the positive meaning. Keep the r before -ly.

Pregunta 7: Mostrar respuesta y explicación

Respuesta: reduction

REDUCE → reduction.

The article ‘a’ needs a singular noun. Repairing the objects created less waste, so we need reduction, in the phrase ‘a reduction in waste’. Notice the spelling change from reduce to reduction; it is not reducetion.

Pregunta 8: Mostrar respuesta y explicación

Respuesta: understanding

UNDERSTAND → understanding.

In ‘a much better ... of’, the gap names the knowledge the writer gained. Add -ing to understand to make the noun understanding. Here it is a noun, not part of a continuous verb tense.
