I request that folks who post sentence correction questions underline the part in question.
Some give the sentence and five choices w/o the underline and it makes harder fofr others to understand the questions and solution to the problem.

PLEASE copy questions as they are for benefit of others.

Many posters don't know how to do this.

Here's how: You put (left square bracket, u, right square bracket) before the text you want to underline, and (left square bracket, slash, u, right square bracket) after the text.

Ironically, I can't write the actual characters above - hence my writing out the characters' names in longhand - because the characters would be misinterpreted as instructions!

In any case, a lack of underlines is a minor annoyance, but it's not detrimental to understanding: it's easy to determine at a glance what is supposed to be underlined.
