Fill in the blank with an appropriate option.

My feel don't ________ the ground for the rest of the day.

touch

The correct option to fill in the blank is touch.

The sentence is about someone who is so tired that they cannot even feel the ground beneath their feet. The word "touch" means to come into contact with something physically. It is the most appropriate word to use in this context, as it suggests that the person is so tired that they are not even aware of their surroundings.

The other options are not as appropriate:

• Slab means a thick, flat piece of stone or concrete. It would not be accurate to use "slab" in this context, as the person is not touching a slab of stone or concrete.
• Deal means to have to do with something or someone. It would not be accurate to use "deal" in this context, as the person is not dealing with the ground beneath their feet.
• Purify means to make something clean or free from impurities. It would not be accurate to use "purify" in this context, as the person is not purifying the ground beneath their feet.
