find the a b c or d which has a different sound in the part underlined 1 a culture b musical c communal d cement

To find the word with a different sound in the underlined part, we need to analyze the sounds of the underlined parts of each option:

1. a) culture - the underlined part "cul" has the sound /ʌl/
2. b) musical - the underlined part "mus" has the sound /juː/
3. c) communal - the underlined part "com" has the sound /kɒm/
4. d) cement - the underlined part "ce" has the sound /sɪ/

Now, looking at these sounds:

- "culture" has the sound /ʌl/
- "musical" has the sound /juː/
- "communal" has the sound /kɒm/
- "cement" has the sound /sɪ/

The sound "mus" in "musical" stands out because it is pronounced with a /juː/ sound, whereas the others have a distinct vowel or consonant sound that does not match this. Hence, the answer is b) musical, as it has a different sound in the underlined part compared to the others.
