Arrange the following words in a logical sequence. 1. Mosquito 2. Cat 3.…

Concept: A "logical sequence" item asks you to place a set of items along ONE governing attribute, chosen so that a single consistent direction (increasing or decreasing) holds between every pair of neighbours in the final order. Here, the governing attribute is physical body size, spanning an insect, a reptile, and three mammals of very different scales.

1. Identify the governing attribute being tested: the relative body size of the five living things named in the stem.

2. Rank each item by its typical, everyday-observed size, not an atypical outlier of that category: Mosquito (a few millimetres) is by far the smallest; a common house/garden Lizard is clearly bigger than a mosquito but still well below a domestic cat; Cat sits above the lizard but well below the farm/wild mammals; Cow is a large farm mammal, clearly bigger than a cat; Elephant is the largest land animal among the five.

3. Map that size ranking onto the item numbers given in the stem: Mosquito = 1 (smallest), Lizard = 3, Cat = 2, Cow = 4, Elephant = 5 (largest).

4. Write the item numbers out in that rank order to get the final sequence.

Cross-check: Confirm the sequence holds pairwise for every neighbour — insect-to-reptile, reptile-to-small-mammal, small-mammal-to-large-mammal, and large-mammal-to-largest-mammal — using ordinary, representative sizes for each species (not an exceptional variety such as a Komodo dragon, which the stem does not specify). None of the other three candidate orderings hold this relation across every neighbouring pair; each breaks the size direction at some point.

Sequence: 1, 3, 2, 4, 5
