The final three months of the year see a dramatic fall in precipitation, to a low of about 10mm in December, and a steady drop in temperatures back to the January average.
the passage is from the writting sample considered to be 9 band which describes the climograph given above. My question is that, does the final clause in bold have to be considered along with the begining part of the passage (The final three months of the year see) and as a result it should be read and construed as ; "The final three months of the year see a steady drop in temperature back to the January" ?
Actually my aim is to determine what the exact role of "back to" here is? Is it verb of the subject - "a steady drop" or adverb modifier of "a steady drop" ? Looking forward to having your responses.
p.s - Don't know how to tag this question so it would be appreciated if anyone edit it and add releated tags.
