Which is a complete sentence?
a. navajo women demonstrate weaving techniques.
b. a house specialty, such as barbecued chicken and ribs.
c. named for an early park outfitter and guide.
d. the cowboys and miners that lived there long ago.

A simple sentence contains the basic element that make a sentence and that is a subject and a predicate. The complete sentence in the choices above is letter A with the sentence: Navajo women demonstrate weaving techniques. Because there is a subject ‘Navajo women’ and a predicate ‘demonstrate weaving techniques’. The rest of the sentences are clauses or are wither subjects only or predicates only. For example sentence B: A house specialty, such as barbecued chicken and ribs, is still a clause and lacks a predicate since ‘such as barbecued chicken and ribs’ are examples or an addition to the subject ‘house specialty’.
