Statement: 'All agricultural drones equipped with multispectral cameras can detect vegetative water stress. No tractor without GPS can perform autonomous auto-guidance.'
Which of the following deductions are logically valid?
Options:
(A) A drone that cannot detect vegetative water stress lacks a functioning multispectral camera (or calibrated sensor)
(B) Any tractor executing autonomous auto-guidance must be equipped with GPS
(C) All tractors equipped with GPS can detect water stress
(D) Drones with thermal sensors are banned from farm use
Answer Key:
A, B
Step-by-Step Solution & Explanation
Statements give: Drone with multispectral -> can detect stress (contrapositive: cannot detect -> lacks sensor); Tractor without GPS -> cannot auto-guide (contrapositive: can auto-guide -> has GPS). Options A and B are valid contrapositives.
