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.
4. If there are two or more nouns and the possession is joint, the apostrophe and s follow the last noun. George and Martha's car is in the shop. This means they both own the same car together. 5. If there are two or more nouns and the possession is not joint, an apostrophe and s are added to each noun to show possession. George's and Martha's cars are in the shop.
