   Hint

   Think about crops commonly found in salty environments.

4. 4.

   True or False: Sensitive crops show no yield reduction in saline conditions.

5. 5.

   Examine how varying salinity levels could impact a farmer's decision in crop selection in a coastal saline region.

   Hint

   Think about the difficulties faced by farmers in saline areas.

6. 6.

   Hint

   Remember the yield reduction information and apply it to your calculation.
