(b) Content of answer. The answer shall include:

(1) A statement that the respondent admits, denies, or does not have and is unable to obtain sufficient information to admit or deny each allegation; a statement of a lack of information shall have the effect of a denial; any allegation not expressly denied shall be deemed to be admitted;
