Step 1: Understand the tone of the sentence.
The approach is described as "visionary," which suggests positive, courageous qualities.
Step 2: Analyze the option for the first blank.
Words like "bold," "daring," and "innovative" imply courage and originality. "Conventional," "conservative," and "timid" imply caution or lack of innovation, which do not fit well.
Step 3: Analyze the second blank.
The sentence says "both _________ and visionary," indicating the second blank should align with the first in positive, courageous connotations.
Step 4: Final choice.
"B) bold" and "D) daring" best fit the meaning of a visionary, courageous approach.
