Concept:This question tests your ability to identify the same consonant sound or consonant cluster in different words.
Explanation:In "marks", the underlined letters
ks are pronounced together as
/ks/.
This is a cluster made of the
/k/ sound and the
/s/ sound.
Now compare the sound in each option.
"Axe" is pronounced
/æks/, so it clearly contains the exact
/ks/ sound at the end.
"Exhaust" is pronounced
/ɪɡˈzɔːst/, which contains
/ɡz/, not
/ks/.
"Mosque" is pronounced
/mɒsk/, and its ending is
/sk/, which is the reverse order.
"Exist" is pronounced
/ɪɡˈzɪst/; the letter
x here gives
/ɡz/, not
/ks/.
Therefore, only "axe" shares the same consonant sound
/ks/ as the underlined letters in "marks".
Answer:B. axe
