Arrange the following words as per their order in an English dictionary and choose the correct code: 1. Syringe 2. Syphilis 3. Syncretism 4. Synarchy 5. Submerge.

Introduction / Context:
This question requires arranging several words beginning with S Y in dictionary order. Because the words are somewhat unfamiliar and quite similar, careful letter by letter comparison is important. Such questions test both your patience and your methodical approach to alphabetical ordering.

Given Data / Assumptions:

• Words: 1. Syringe 2. Syphilis 3. Syncretism 4. Synarchy 5. Submerge.
• We must order them as they would appear in a dictionary.
• The answer is expressed as a sequence of these numbers.
• Standard English alphabetical rules are assumed.

Concept / Approach:
The main idea is:

• Compare the first letter. If they match, move to the second, then to the third, and so on.
• The first letter position at which two words differ decides their relative order.
• Words starting with different letter pairs such as SU versus SY will be grouped accordingly.

Step-by-Step Solution:
Step 1: Note the first two letters. Submerge begins with S U, while Syringe, Syphilis, Syncretism, and Synarchy all begin with S Y. Step 2: Since U comes after Y in the alphabet, all S Y words will come before Submerge. Therefore Submerge (5) must be the last item in the dictionary among these five words. Step 3: Now focus on the S Y group: Syringe (1), Syphilis (2), Syncretism (3), Synarchy (4). Step 4: Compare the third letter of each S Y word. Syringe has R (S Y R), Syphilis has P (S Y P), Syncretism has N (S Y N), and Synarchy also has N (S Y N). Step 5: Among N, P, and R, N comes first, then P, then R. So the S Y N words (Syncretism and Synarchy) will come before Syphilis and Syringe. Step 6: Now compare Syncretism (3) and Synarchy (4), both starting S Y N. At the fourth letter, we have C in Syncretism (S Y N C) and A in Synarchy (S Y N A). Since A comes before C, Synarchy (4) must come before Syncretism (3). Step 7: Next compare the remaining S Y words: Syphilis (2) and Syringe (1). Both begin S Y, but Syphilis has P as the third letter and Syringe has R. Since P comes before R, Syphilis (2) comes before Syringe (1). Step 8: Combining all comparisons, the dictionary order becomes Synarchy (4), Syncretism (3), Syphilis (2), Syringe (1), Submerge (5). As a code, this is 4,3,2,1,5.

Verification / Alternative check:
Write the S Y words grouped as Synarchy, Syncretism, Syphilis, Syringe. The third letters group as SYN..., SYP..., SYR..., which is a neat N, P, R progression. Adding Submerge, which starts with SU and therefore comes after all the S Y words, confirms that 5 is last. This matches the derived code 4,3,2,1,5.

Why Other Options Are Wrong:
Option 5,4,3,2,1 starts with Submerge, but SU words should come after all SY words. Option 5,3,4,1,2 again places Submerge first and misorders Synarchy and Syncretism. Option 4,1,2,3,5 places Syringe and Syphilis in the wrong internal order relative to Syncretism. Option 3,4,2,1,5 swaps Synarchy and Syncretism and therefore contradicts the alphabetical comparison at the fourth letter.

Common Pitfalls:
The main pitfalls are confusion due to similar starts and unfamiliar medical terms, and ignoring later letters after seeing the same first few letters. Another common mistake is to misjudge the position of SU relative to SY. Always compare characters systematically and remember that Y comes before U.

Final Answer:
The correct dictionary sequence is Synarchy, Syncretism, Syphilis, Syringe, Submerge, encoded as 4,3,2,1,5.
