Arch handbook and articles: Reword sentences beginning with 'Because...'

These sentences can either be or be mistaken for being sentence
fragments. While it is perfectly reasonable to use subordinate
conjunctions conversationally, as long as both clauses are explicitly
used in the same sentence, the handbook or articles are not written
in this style.
