Study hint
The exercise is short but do not concentrate on solving the task only.
When you do an exercise, try to learn one, two, three new words from the sentences.
Below you can see my suggestion for what can be memorized after doing this exercise.
You can learn new words by checking their meaning but I think the chances to remember the new words grow when you learn them in context, i.e. with other words they are usually used with. The most important are the verbs. However, if you learn the adjectives, then your English will sound more proficient.
