Answer:
D) They can increase the reaction rate for a given reaction by a thousand-fold or more.
Explanation:
Enzymes are like catalysts with the only difference that they are bio-molecules. Biochemical/chemical reactions are slow because of 'transition state barriers' which require a lot of energy to overcome so enzymes rather than overcoming transition state barrier provide an alternate pathway for biochemical reactions which require comparatively less energy. Thus presence of an enzyme leads to an increase in reaction rate because alternate pathway which requires less energy makes the rate of chemical reaction rapid by a thousand-fold or more. 
 
        
             
        
        
        
Interviews: 
- Objective: purpose is to obtain Information 
- Minimal legal requirements; no rights warnings 
- cooperative relationship between interviewer and subject likely 
- no guilt 
- moderate planning 
- Most Important: private and semiprivate; distraction could cause witness to forget key info 
- Interrogations 
- Objective: purpose is to test information already obtained, obtain valuable facts; eliminate the innocent; identify the guilty; obtain a confession 
- extensive pre interrogation legal requirements; rights required 
- hostile relationship likely 
- guilt suggested 
- extensive planning 
- absolute privacy
        
             
        
        
        
They are like that because they can't always be faulty and may have at least some spark of truth to this theory also as stated earlier a theory in scientific terms is just an observation so it can't really be turned down hence theory.
