To assimilate knowledge means to fully absorb and adopt information in a way that integrates it into one's existing understanding or framework of knowledge. When a person assimilates knowledge, they not only learn new information but also understand it deeply, making connections with what they already know. This process often involves critical thinking and active engagement with the material, leading to a more comprehensive understanding.

This concept of assimilation is different from simply memorizing information without grasping its meaning, which is indicated in another choice. Memorization focuses on recall rather than understanding. Similarly, some options suggest ignoring new information or critiquing it without the intention of integrating it, which also diverges from the idea of assimilation that emphasizes integration and incorporation into one’s understanding. Therefore, the definition of assimilating knowledge aligns clearly with the correct answer, highlighting the importance of engaging with and fully comprehending new information.
