Explanation:

- The sentence revolves around the State Government not being able to handle or manage an increase in teachers' salaries.

- Option 1: get – This word means to obtain or receive, but doesn't fit logically here. The issue is about financial capability, not about acquiring salaries.

- Option 2: afford – This implies being able to financially support the salary increase. It's apt as it captures the core issue of budget limitations.

- Option 3: spare – Refers to having extra resources or time, which doesn't clearly express financial incapacity to handle an expense.

- Option 4: stand – Means to endure or tolerate, which can imply discomfort but isn't about financial ability.
