Three subject verb disagreement allegedly recovered from the legendary king solomons mines,

Here are the examples of three subject verb disagreement in this text:

1. "the fate of the diamond ... were unknown" - it should be changed to was unknown

2. " neither time nor conflict have dimmed" - it should be changed to has dimmed

3. " the twin eighty-year-old brothers suggests" - it should be changed to suggest

Subject and verb have to agree when it comes to the number - if the subject is singular, the verb has to be singular as well. If the subject is plural, the verb has to be plural.
