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.
Grand juries consist of 16 to 23 jurors (it's up to the judge), but 12 yes votes are always required for an indictment. Grand jurors are selected from the same voter registration rolls used to pick ordinary federal jurors. Hundreds are summoned when a new jury is needed and then the judge excuses people who would find it especially burdensome to give up two or three days a week for a year and a half. As a result, grand jurors are generally retirees, the unemployed, or government employees.
