Please check all paraphrase which could replace the blue word in the context shown, using your best judgement. The paraphrase should retain the meaning of the original phrase and make sense in context. Most sentences will have at least one good paraphrase, but some will not. If none of the paraphrases listed fit the context shown, select NONE.

It is okay if the paraphrased sentence is contains small grammatical errors, as long as they do not drastically alter the meaning. E.g. the following is an okay paraphrase:

The boy is running.

The boys is running.

but the following is a bad paraphrase:

I am running.

You are running.

It is okay if the paraphrased sentence contains more/less detail than the original sentence, as long as it does not drastically alter the meaning. E.g. the following is an okay paraphrase:

The person is running.

The boy is running.

but the following is a bad paraphrase:

The cells undergo development.

The cells undergo economic development.

The paraphrase should make sense in the particular sentence shown. E.g. the following is a bad paraphrase, even though center might be a good paraphrase for heart in some other contexts.

The heart is an organ.

The center is an organ.

These HITs will be quality controlled. If you are unsure whether or not you are doing them well, we recommend you do a small number and wait for feedback before continuing.

Thank you in advance!
