Answer 2

Answer:
Design for safety.

Step-by-step explanation:
When a structural material is brittle, it can fail suddenly, while a malleable material fails gradually.
When structural failure could be life threatening, it is prudent to use more of the malleable material rather than the brittle material. Doing so enables the failure mode to be more easily detected and to save lives.
