In pragmatics (linguistics), entailment is the relationship between two sentences where the truth of one (A) requires the truth of the other (B). For example, the sentence (A) The president was assassinated. entails (B) The president is dead.
Other Statutes Applicable to Newspaper Carriers. Minimum age/ working hours: Newspaper carriers must be at least 11 years old to distribute or sell newspapers. Any minor under 16 years of age is permitted to work before 5 a.m. or after 8 p.m. (including weekends). Just verify this with current law.
The length of time entirely depends on what carrier you use and what class of delivery you use. If you send a letter via the US Postal Service, a First Class letter up to 13 ounces will be delivered within three days in most cases and Express Mail is overnight delivery to most US addresses.
