Final answer:
Although the question is not directly connected to Biology, the standard ink colors for academic work are usually blue or black, unless otherwise specified by the instructor. The student should look for bolded answers in the instructional materials for clarity.
Step-by-step explanation:
The question appears to be about the standards for completing assignments in a classroom setting, but based on the provided information, it does not seem to be directly related to Biology or the concept of color and color vision. Typically, standard colors for writing in an academic context are blue or black ink.
These colors are used because they are professional and provide high contrast for easy reading and photocopying. However, this convention can vary based on teacher preferences or institutional guidelines.
If this is a question from a worksheet or a test, the correct answer might be indicated by the use of bold text, as mentioned in the information given. Therefore, the student should check for the bolded answer in his or her materials, or else follow the specific instructions provided by the educator.
