Examples

• The extendibilities of different materials vary greatly depending on their molecular structure.
• Engineers tested the extendibilities of the new polymer to ensure it met safety standards.
• The software's extendibilities allow developers to add new features without rewriting core code.
• Researchers compared the extendibilities of various fabrics for use in athletic wear.
• The contract's extendibilities were carefully negotiated to allow for future modifications.
