Hey, is Greg not telling a story about scientists that they will be happy with more information as far as I know scientists are more skeptical about the particular information they want and here clearly they are getting inaccurate information.
The word “wealth” generally has positive connotations. Whenever you say “the wealth of” something, it generally means a high amount of something positive.
So, the blank here has to convey a positive attitude to the extra data.
