Question

Using letters printed in the lower left-hand corner of each card, write the sequence of letters from the youngest layer to the oldest layer.

a) XYZ
b) WXY
c) UVW
d) TUV

Answer 1

The sequence of letters from the youngest layer to the oldest layer is d) TUVWXY.

Step-by-step explanation:

To determine the sequence of letters from the youngest layer to the oldest layer, we need to arrange the given sequences in ascending order. First, we compare the first letters of each sequence: T, U, U, and W. Since T comes before U, the sequence starting with T is the youngest layer. Next, we compare the second letters of each sequence: U, V, V, and X. Since U comes before V, the sequence starting with TU is younger than the others. Finally, we compare the third letters of each sequence: V, W, W, and Y. Since V comes before W, the sequence starting with TUV is younger than the others. Therefore, the correct sequence from youngest to oldest is TUVWXY.

This can also be represented as:

TUV UVW UVW UVW

Therefore, arranging them in ascending order gives us TUVWXY as the correct sequence from youngest to oldest.

In conclusion, by comparing the letters in each position of the given sequences and arranging them in ascending order based on their positions, we find that the sequence from youngest to oldest is TUVWXY.
