In this test you will be asked to listen to 45 pairs of sentences.
Your task will be to judge which of the two sentences you think sounds the most natural.
We ask that you listen to both sentences in each pair at least once, and no more than twice, and then make your judgement.
As the differences can be quite subtle, please only pick no preference if you cannot tell a difference between the two sentences - trust your intuition as to what is best.
Please complete the survey in one sitting, but feel free to take small breaks when needed, you will not be able to return to it later.
