Arrange the words Launch, Laugh, Lattice, Latent and Latitude in dictionary order and select the correct sequence.

Introduction / Context:
This question requires you to arrange five words in dictionary order: Launch, Laugh, Lattice, Latent and Latitude. Several of these words begin with “Lat”, while others begin with “Lau”, so you must carefully compare letters to decide the correct order. Such tasks are standard in verbal reasoning exams and help measure your precision in handling alphabetical comparisons for similar looking words.

Given Data / Assumptions:
Index mapping:
1: Launch
2: Laugh
3: Lattice
4: Latent
5: Latitude
Options show sequences like 4,5,3,2,1 that represent potential dictionary orders.
We assume standard dictionary rules and that shorter words preceding longer ones only matters if one is an exact prefix of the other.

Concept / Approach:
First, group the words according to their first three letters. Words beginning with “Lat” will come before words beginning with “Lau”, because the third letter “t” comes before “u” in the alphabet. Inside each group, we then compare subsequent letters to derive their relative order. By handling the “Lat” group and “Lau” group separately, the problem becomes simpler and less error prone.

Step-by-Step Solution:
Step 1: Group the words by their first three letters. Latent (4), Lattice (3) and Latitude (5) start with “Lat”. Launch (1) and Laugh (2) start with “Lau”. Since t comes before u, all “Lat” words must appear before the “Lau” words in dictionary order. Step 2: Order the “Lat” words. Latent is L a t e n t. Lattice is L a t t i c e. Latitude is L a t i t u d e. Compare after “Lat”. For Latent, the next letter is “e”. For Latitude the next letter is “i”. For Lattice the next letter is “t”. Alphabetically, e comes before i, which comes before t. Therefore Latent (4) comes first, Latitude (5) second and Lattice (3) third within the “Lat” group. Step 3: Order the “Lau” words. Laugh is L a u g h, Launch is L a u n c h. They share “Lau”. The next letter is “g” in Laugh and “n” in Launch. Since g comes before n, Laugh (2) comes before Launch (1). Step 4: Combine all positions. First the “Lat” group in the order 4, 5, 3. Then the “Lau” group in the order 2, 1. Complete dictionary order: Latent (4), Latitude (5), Lattice (3), Laugh (2), Launch (1). This is represented as 4,5,3,2,1.

Verification / Alternative check:
List the words explicitly: Latent, Latitude, Lattice, Laugh, Launch. Check that each transition respects alphabetical comparison. Within the “Lat” group, e in Latent precedes i in Latitude, and both precede t in Lattice. Within the “Lau” group, Laugh precedes Launch because g is earlier than n. Since no alternative option reproduces this entire order, 4,5,3,2,1 must be correct.

Why Other Options Are Wrong:
Any option that places a “Lau” word before a “Lat” word violates the rule that t comes before u in the third letter position.
Options that put Lattice before Latent or Latitude ignore the fact that “L ate” and “L ati” precede “L att”.
Sequences that place Launch before Laugh fail to respect that g comes before n.
Thus only 4,5,3,2,1 consistently follows dictionary ordering.

Common Pitfalls:
Many candidates only check the first three letters and then rely on intuition for the rest of the order, leading to mistakes inside the “Lat” or “Lau” groups. Another common pitfall is to read quickly and miss that Laugh and Launch differ in the fourth letter, not the third. Taking a systematic, letter by letter approach avoids confusion and ensures that even subtle differences in later positions are not overlooked.

Final Answer:
The correct dictionary order is Latent, Latitude, Lattice, Laugh, Launch, corresponding to the sequence 4,5,3,2,1.
