1     terms of the attitude to work, as a brilliant chemist, Mr. Brown devoted himself     2     (entire) to his scientific research. He was always conducting each experiment so carefully.

The idea of writing a poem might feel frightening     1     (initial) — do you need to follow a certain structure, does it need to have a rhyme, or do you need to have recited a dictionary to be a “proper” poet?

In our study we asked people if they had had Covid-19 themselves. Those people     1       responded yes were 3.9 times more likely to be highly resilient. That is to say, the more exposed you were, the    2    (high) your resilience levels. This strongly suggests that we discover our resilience only when we    3     (force) to meet unavoidable suffering full in the face. The real is almost always less scary than the imagined, and the reality of the disease helps you with knowing       4       you’re capable of.
