Final answer:
The sentence completion question from English requires additional context to accurately fill in the blank about where the 'five DHIs' planned to attend as their human selves.
Step-by-step explanation:
The question involves completing the sentence with the most appropriate word or phrase. The sentence is "The five DHIs planned on attending ________ as their human selves." In English, 'DHI' is an acronym commonly used to refer to 'Disney Host Interactive' or 'Digital Hologram Imaging,' from the Kingdom Keepers series by Ridley Pearson. However, without additional context, it's unclear which specific event or location the DHIs planned to attend as their human selves. Therefore, to insert the correct word or phrase into the blank, more context is needed surrounding the story or setting in which they are found.
