Pretend you are a teacher preparing a quiz for the text I will provide. 
            Each quiz question should follow the format below. 
            Ensure that you carefully recheck the questions and answers for accuracy. 
            The output should be a ready-to-use list of dictionaries for the Python eval function:

            [

                    "question": "WRITE THE QUESTION HERE",
                    "options": ["A) OPTION_1", "B) OPTION_2", "C) OPTION_3", "D) OPTION_4"],
                    "answer": INDEX_OF_CORRECT_ANSWER_IN_OPTIONS_LIST,
                    "explanation": "EXPLAIN WHY THE ANSWER IS CORRECT"

b. 
The second digit is located at the right side of the number and indicates the 
number of the tooth in the quadrant. 
      The two digits should be pronounced separately 
In the permanent dentition.                            In the deciduous dentition.

3)The universal numbering system (American numbering system):. 
The number is always preceded by the sign # for the permanent teeth, while for the 
deciduous teeth, it is preceded by the sign #d to designate that the system used is the 
universal system.

Anatomical Landmarks of the Crown  
A - Crown Elevations  
(I)   Lobe.  
It is one of the primary centers of calcification and growth formed during the crown 
development. Each tooth begins to develop from four lobes or more.    
The pulp chamber has pulp horns corresponding to these lobes.  
 
 
 
 
 
 
 
 
 
Only some maxillary third molars have as few as 3 lobes. Peg-shaped maxillary lateral 
incisors and some supernumerary teeth have less than three lobes. 
THE MATURE FORMS OF LOBES ARE: 
1. Mamelones ,2. Cingulum ,3.Cusps  
1. Mamelones: They are three small round projections of enamel present in the incisal third 
of newly erupted incisors. 
After normal use, eventually the mamelones wear down into a flat edge.

2.Cingulum:  
It is the enlargement or bulge on the cervical third of lingual surface of the crown in 
anterior teeth (incisors and canines). It is also called the linguo-cervical ridge 
 
3.Cusps:  
They are pyramidal projections on the incisal portion of the canine and on the occlusal 
surfaces of the premolars and molars teeth. 
(II) Tubercle  
• It is a small elevation. It is produced by excessive formation of enamel.  
• Tubercle is also called cusp of carabelli ,it is noticed at the palatal surface of E & 6 (on 
the mesio-lingu
