Remember that a dependent clause always contains a subject and a verb, but it cannot stand by itself. 1  Adverb clauses provide information about what is going on in the main (independent) clause: where, when, or why. 2  Adjective clauses work like multi-word adjectives. 3  Noun clauses can do anything that nouns can do.
An alternate juror is a spare, not unlike the spare tire for your car that rides along with you wherever you drive but is only used if one of your regular tires fails. Similarly, an alternate juror sits and listens to evidence just like the other jurors but only deliberates and votes if one of the sitting jury members is unable to serve.
Petit or trial jurors are on-call for a one (1) month term of service or occassionally longer depending on the court's jury needs. This does not mean that you will serve on juries for an entire one (1) month period.
