Take a look at the sentence again:
When Carol went hunting through the kitchen for a midnight snack, she found
a stale chocolate chip cookie __________ in a crumpled bag on top the refrigerator.
The stale Oreo is resting in the bag. Thus, you need a form of lie. The blank requires a present participle. Consult the table below or review the rules.
Lieing, the form you chose, does not appear on the table; it is a spelling error.
| Infinitive | Definition | Simple Present | Simple Past | Past Participle | Present Participle |
| to lay | to put something down | lay(s) | laid | laid | laying |
| to lie | to rest or recline | lie(s) | lay | lain | lying |
