If the IRS hasn't raised any issues about your 2005 tax return by now, it is safe to shred it. Last, you should keep any tax return that includes a claim for deducting worthless securities for seven years. If you've lost or discarded a tax return and later need a copy, don't worry.
Rule 2 in the âApostrophesâ section says, âUse the apostrophe to show possession. Place the apostrophe before the s to show singular possession.â. Since âworldâs biggestâ is singular possessive, you need to use âs regardless of which noun follows it.
In possessives, the placement of the apostrophe depends on whether the noun that shows possession is singular or plural. Generally, if the noun is singular, the apostrophe goes before the s. The witch's broom. If the noun is plural, the apostrophe goes after the s: The witches' brooms. However, if the word is pluralized without an s, the apostrophe comes before the s: He entered the men's room with an armload of children's clothing.
