Question

which two properties do these two objects have in common? ceramic mug glass flask select the two best answers. smooth fragile opaque transparent

Explanation:

1. Analyze "smooth": A ceramic mug and a glass flask typically have smooth surfaces (ceramic is glazed smooth, glass is naturally smooth).
2. Analyze "fragile": Both ceramic and glass are brittle materials, so they are fragile (can break easily).
3. Eliminate "opaque": The glass flask is transparent, not opaque.
4. Eliminate "transparent": The ceramic mug is opaque, not transparent. So the two common properties are smooth and fragile.

Answer:

smooth, fragile
