Answer:
The two answers for the words that you have posted on this question, with their correct mnemonic group, would be as follows:
1. Deplor_?__: Given that this word ends with an "e" then in this case the rule that applies would be the one in Group II: When the root is a full word except for a final "e", the forms usually are spelled with - able. Therefore, the answer will be: DEPLORABLE.
2. In this second case, we have the word GROUP, which is a full word, to which we will have to add an ending. In this case, because the root is a full word, then the rule will be the one in Group I. If the root is a full word, the ending is usually - able. Therefore, the correct answer would be: GROUPABLE.
