For the question, choose the option that has the same consonant sound as the ones represented by the letter(s) underlined.
shadow
Answer Details
The underlined letters in shadow are sh, which produce the voiceless postalveolar fricative /ʃ/. This is the "shushing" sound heard in words like "ship," "shoe," and "shout."
Now consider each option:
sure - the "s" in "sure" is pronounced /ʃ/, exactly the same sound as "sh" in "shadow."
match - the "tch" produces /tʃ/ (an affricate), which combines a stop with a fricative and is a different sound from /ʃ/.
chemistry - the "ch" is pronounced /k/, not /ʃ/.
scheme - the "sch" is pronounced /sk/, not /ʃ/.
The correct answer is sure, because the "s" in "sure" produces the same /ʃ/ sound as "sh" in "shadow."
