Good. However note the following:

@& Instructions request that you insert your responses into a copy of the original web document. You appear to have eliminated some of the text from the original document.
The original text includes certain strings of characters that allow me to efficiently isolate your insertions from the rest of the text, allowing me to review much more student work, much more accurately, than would otherwise be possible.
These and other characters are also used as triggers in collecting databases of student responses, and in some instances the lack of these characters can cause your document not to post at all.
If so requested below, you should resubmit this document, and insert your responses into a complete, unaltered copy of the original document. If you are not specifically requested to do so on this document, it won't be necessary, but you should follow this practice on all future submissions.
It is also possible that you have submitted other documents in which you have removed information from the original, rather than inserting your responses into an unaltered copy of the document. If this is the case, you should resubmit those documents, with your responses copied into complete copies of the originals.
