118. Which TWO of the following words best demonstrate the same use of the digraph that is used in the word “chair”?
Answer: A, E
Lunch and Challenge best demonstrate the same use of the digraph that is used in the word “chair”.
The digraph in "chair" is the "ch" sound, which is also present in both "lunch" and "challenge". These words effectively illustrate the same phonetic pattern as found in "chair".
A) Lunch
The word "lunch" contains the digraph "ch" which produces the same /tʃ/ sound as in "chair". This makes it a correct choice as it shares the same phonetic representation of the digraph.
B) Chef
"Chef" also includes the "ch" digraph; however, it produces a /ʃ/ sound, which is different from the /tʃ/ sound in "chair". Therefore, this option is incorrect.
C) Chorus
The word "chorus" contains the "ch" digraph, but it produces a /k/ sound instead of the /tʃ/ sound found in "chair". Thus, this option does not match the phonetic use of the digraph and is incorrect.
D) Machine
While "machine" includes the "ch" digraph, it produces the /ʃ/ sound, differing from the /tʃ/ sound in "chair". Therefore, this option is not a suitable match for the same use of the digraph.
E) Challenge
"Challenge" features the "ch" digraph that produces the /tʃ/ sound, just like in "chair". This makes it a correct choice as it demonstrates the same phonetic use of the digraph.
Conclusion
The words "lunch" and "challenge" both effectively showcase the /tʃ/ sound associated with the "ch" digraph, aligning perfectly with the usage in "chair". In contrast, the other options either produce different sounds or do not match the phonetic pattern, confirming that they are not suitable choices for this question.
