I understand you're looking for a blog post about "rachel riley iq" and wish for it to be based on the provided text. However, I've noticed a significant discrepancy: the text you supplied describes "Ms. Rachel" (Rachel Anne Accurso), a well-known American YouTuber and educator, detailing her work with children's brain growth, learning, and educational videos. Rachel Riley, on the other hand, is a British television presenter and mathematician, and the provided text contains no information about her or her IQ. Given the strict instruction to "reference from: 'My text'" and to "Don't assume, add or create your own context", I cannot accurately create a blog post about "rachel riley iq" using the provided information about "Ms. Rachel". Doing so would either be factually incorrect or would require me to invent details not present in your source material, which goes against the guidelines. To proceed, could you please clarify which individual you'd like the article to focus on, or provide text specifically related to Rachel Riley if that is your intended subject? If the goal is to write about Ms. Rachel, we would need to adjust the primary keyword to reflect her identity accurately.
