This is because many breakthroughs come up when people venture 20 their usual routines or areas of expertise.
答案：(D) beyond
venture beyond 意為「冒險走出…的範圍」，本句指許多突破來自於人們敢於跨出慣常的做事方式與專業領域；into（進入）語意方向相反，without（沒有）、under（在…之下）都不合。
答對率 32%。
beyond 你大概只用在具體的距離或時間（beyond the mountains），較少用在抽象範圍上。把 beyond 想成「越過那條界線」，抽象用法就通了：go beyond（超出）、beyond one's reach（構不著）、beyond doubt（無庸置疑）。
前一句 Another way to increase creativity is to take risks. 已經定調；本句說突破來自「走出」慣常的做事方式與專業領域。填 into 語意剛好相反——走進自己的老習慣裡不會有突破。下一句 learning new skills or traveling to new countries（學新技能、去沒去過的國家）也是往外走。
venture beyond（冒險跨出）、go beyond（超出）、beyond one's control／reach（無法控制／構不著）、step out of one's comfort zone（走出舒適圈）。
