Correct the following sentences: 

The original sentence contains a common grammatical error involving the misuse of the verbs 'lie' and 'lay'. Understanding the distinction between these two verbs is crucial for accurate English usage.

    
• Lie (intransitive verb): This verb means to recline, rest, or be in a horizontal position. It does not take a direct object.
    
        
• Principal parts: lie (present), lay (past), lain (past participle), lying (present participle)
        
• Example: I need to lie down. Yesterday, I lay on the sofa.
    
    
• Lay (transitive verb): This verb means to put or place something down. It always requires a direct object.
    
        
• Principal parts: lay (present), laid (past), laid (past participle), laying (present participle)
        
• Example: Please lay the book on the table. She laid the baby in the crib.
    

In the given sentence, "Karim was exhausted so he decided to lay down for a little while," Karim is performing the action of reclining himself. Therefore, the intransitive verb 'lie' should be used. Since the structure is "decided to + base form of the verb (infinitive)," the correct form is 'lie'.

The error in the original sentence lies in the use of the infinitive "to stay" after the causative verb "make." When "make" is used in the active voice to mean "force" or "cause someone to do something," it is followed by an object and then the base form of the verb (also known as a bare infinitive), not the "to"-infinitive.

The structure is: Subject + make + Object + Base Form of Verb.

Examples:

    
• She made him laugh. (Not: She made him to laugh.)
    
• My parents always make me do my homework. (Not: My parents always make me to do my homework.)

Therefore, "to stay" must be corrected to "stay."
