I have a question about using that the in a sentence. It is my understand that, "the" is used when the noun has been identified before or if it is specifically related to a known subject. I have had the discussion numerous times as to whether one uses "that the..." or just uses "that..." in sentences. I typically use the two words together when either one does not make sense without the other. For example, I used it in the following manner in my document.
Prior to conducting these surveys, we recommend that the applicant’s consultant contact the Service to discuss appropriate survey methodology.
The sentence would not make sense without both words being used. However, in the sentence below, one could make sense of the sentence by just using the term, "the" without the "that".
Second, that the City should require, and only accept as valid, those assessments that include surveys that are performed by qualified individuals during appropriate seasons when sensitive species would likely be detected.
My question is, which way is proper?
