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.
The big question is whether to put the apostrophe before the s or after the s. The basic rule is this: the apostrophe goes before the s for a single possessor (e.g., one dog's kennel) and after the s when it's more than one possessor (e.g., two dogs' kennel). Note: In these examples, the dog and dogs are the possessors.
