Question
1. In Excerpt 2, which column displays categorical values?
a. column 1
b. column 2
c. column 3
2. In Excerpt 2, which column shows quantitative values?
a. column 1
b. column 2
c. column 3
3. In Excerpt 2, the table is showing evidence for which argument?
a. According to ASTM Standard F138-13a [7], this composition meets the requirement of 316L stainless steel, as shown in the third column of Table 1. Excerpt 2 (page 32) According to the provided information, the plate was manufactured from 316L stainless steel [4]. Chemical analysis, metallographic observations and hardness tests were performed to validate this information. The plate was first cut into samples according to the schematic drawn in Fig. 1 . An optical spectrometric analysis of sample #2, based on ASTM E 1086-08 [ 5 l, was conducted to characterize the implant chemistry. Sample #7a was poli shed and etched with a solution composed of 150 mL of distilled water, 50 mL of HCl and 50 mL of HN03. for 90 s to reveal the material microstructure. Sample #7b was used to perform Rockwell C hardness measurements according to ASTM E18-15 [6. The fracture surfaces were observed 4. Experimental results 4.1. Material characterization 4.1.1. Chemical analysis The measured chemical composition of the studied LCP is shown in the second column of Table 1. According to ASTM standard F1 38-13a 171 this composition meets the requirement for a 316L stainless steel, as shown in the third column of Table 1. 316L stainless steel is typically used to manufacture surgical implants [8].

1) categorial values are the one that can take on one of the limited values or the usually fixed number of possible values.
From the table column 3 meets the criteria.
Option C is the right answer.
2) Quantitative values are usually the numerical values like percentage, number , count.
From the table Column 2 meets the criteria.
Option b is the right answer
3) As per the measured composition of the LCP which was studied, it meets the criteris of 316L stainless steel and sane has been providedin the table for reference.
So Option a is the right answer
