Recent Corrections Here is a list of recent corrections to Newsroom101.com, with thanks to those who pointed out the problems. If you find problems in the exercises, please  us. His or her -- One issue requires clarification. A number of items point out that it is incorrect to use a construction such as "Everybody should bring their book to class." The AP Stylebook indicates that, in such situations, you should use "his" rather than "his or her." Thus, it is AP style to write, "Everybody should bring his book to class." In a number of the exercises in Newsroom101.Com, we have made "his or her" the correct choice out of deference to recent decades of effort in reducing sexist language. It is important to note that AP requires the simpler term "his." Thanks to Lauren Raab, I fixed several exercises that misused "badly."  More explanation. Fixed several errors in the explanations in Choose the Right Expression (thanks to Lauren Raab). 10/15/07 Clarified instances of copy edit, copy editor, copy editing, and the verb to copy-edit (with a hyphen). Thanks to Liz Ruskin for pointing out this problem. 07/13/07 Thanks to Angelique Rondeau, Dan Reed, Megan Moore, Angie Weaver, Bridget Weber, Krissi Palmer, Sarah Kenney and students of Debra Gump for spotting typos and questions that needed clarification. Clarified the question and feedback about the size of barrels used to measure oil. Thanks to Patrick Owens at the Richmond Times-Dispatch. 03/26/07 Corrected and clarified the question on telephone numbers (thanks to Katelyn Burkhard). In 2006 AP announced that telephone numbers would now be entered in the form "212-565-9376, ext. 4". Notice the hyphens and the comma. This change might not be in the printed stylebook yet. Thanks to Deb Gump and her students. (02-28-07) Capitalized Web site in Possessives. Thanks to Troy Brakefield, a student at Texas A&M-Commerce. (02-12-07) Hannah Barton at Texas A&M-Commerce pointed out several coding errors in the Confusable Words exercises that caused some correct answers not to be indicated as correct. Fixing them led to replacing a considerable amount of obsolete coding that could have caused problems in modern browsers. Thanks, Hannah. (01/15/2007) "Backyard" is one word in all uses. (10-01-06)
