Answer:
1. A. chemist
2. B. world
Explanation:
The same letter can represent different sounds. When we look at the options for number 1, for example, we realize that the letters "ch" represent two types of sound. The one word in which that sound is different when compared to the others is "chemist". Here, the "ch" has a "k" sound.
The same happens with the word "world" in number two. The letter "o" in it sounds different than it does in the other options. In "fork" and "north", for instance, the "o" is more open.
