Meaning Analysis  
  • World War II combatants gained an advantage over their opponents
    • either by employing a number of new and devastating inventions such as
      • rudimentary flame throwers,
      • tracer bullets,
      • pilotless drones,
    • or having strong leadership and geographic advantage.                              
The sentence says that World War II fighters gained a benefit over their opponents by doing either of the following:
  1. employing a few novel and dangerous inventions such as rudimentary flame throwers, tracer bullets, and pilotless drones.
  2. having strong leadership and geographic advantage.
Error Analysis
This sentence has two parallel lists. And there are errors in both the lists.
1)     The first list as suggested by the presence of the parallel markers “either-or” is “by employing…” and “having strong…” These two entities are certainly not parallel as the word “by” appears only before the first entity and not before the second entity.   
2)     The second list is a nested list in the first entity of the main list. This nested list has three entities – “rudimentary flame throwers, tracer bullets, pilotless drones”. However, this list is not correct because the parallel marker joining the last entity of the list with the first two is missing. The last entity in the list must be preceded by a relevant parallelism marker such as “and”. 
Answer Choices
A
inventions such as rudimentary flame throwers, tracer bullets, pilotless drones, or having strong leadership and geographic advantage 
Incorrect: This choice has the errors stated in the error analysis.
B
inventions, such as flame throwers that were rudimentary, tracer bullets, pilotless drones, or strong leadership and geographic advantage
Incorrect:      
1)     This choice repeats the missing “and” parallelism error of Choice A.
2)     The noun “strong leadership…” is not parallel to “by employing”    
C
inventions such as rudimentary flame throwers, tracer bullets, and pilotless drones, or by having strong leadership and geographic advantage 
Correct:
This is the correct answer choice as it corrects both the parallelism errors spotted in the original sentence. 
D
inventions, such as rudimentary flame throwers, tracer bullets, and pilotless drones, or had strong leadership and geographic advantage
Incorrect:   
This choice has parallelism error.  “Either by employing…” is not parallel to “or had strong leadership…”
E
inventions such as flame throwers that were rudimentary, tracer bullets, and pilotless drones, and by having strong leadership and geographic advantage    
Incorrect: 
Use of “and” before “by having strong leadership…” leads to an idiom error. “Either” should be followed by “or,” not “and”.

Explanation:
The correct answer is option 'C': inventions such as rudimentary flame throwers, tracer bullets, and pilotless drones, or by having strong leadership and geographic advantage.

Reasoning:
- The sentence presents two ways in which World War II combatants gained an advantage over their opponents.
- The first way is through the use of new and devastating inventions, such as rudimentary flame throwers, tracer bullets, and pilotless drones.
- The second way is by having strong leadership and geographic advantage.
- Option 'C' accurately presents both ways, using the correct punctuation and parallel structure.
- The other options either incorrectly combine the inventions with leadership and geographic advantage or do not include all of the mentioned inventions.

Analysis of other options:
a) inventions such as rudimentary flame throwers, tracer bullets, pilotless drones, or having strong leadership and geographic advantage
- This option incorrectly combines the inventions with leadership and geographic advantage, making it grammatically incorrect.

b) inventions, such as flame throwers that were rudimentary, tracer bullets, pilotless drones, or strong leadership and geographic advantage
- This option incorrectly specifies that the flame throwers were rudimentary, which is not mentioned in the original sentence.

d) inventions, such as rudimentary flame throwers, tracer bullets, and pilotless drones, or had strong leadership and geographic advantage
- This option incorrectly uses the past tense "had" instead of the present tense "having" when referring to leadership and geographic advantage.

e) inventions such as flame throwers that were rudimentary, tracer bullets, and pilotless drones, and by having strong leadership and geographic advantage
- This option incorrectly combines the inventions with leadership and geographic advantage, making it grammatically incorrect.

Therefore, option 'C' is the correct answer.
