Let's go through each of the words to identify which one has the underlined part pronounced differently or differs in the position of primary stress:

1. **vegetable** - **'vegetable'** has the stress on the first syllable.
**stripe** - **'stripe'** has the stress on the single syllable.
**cable** - **'cable'** has stress on the single syllable.
**block** - **'block'** has stress on the single syllable.
**blanket** - **'blanket'** has stress on the first syllable.
**fine** - **'fine'** has stress on the single syllable.
**syllable** - **'syllable'** has stress on the first syllable.

Here, **vegetable** is different in its syllable structure and primary stress, but it’s stressed correctly in the context of other words.

2. Fine, syllable, and block share the same stress position.

In question 8:
**always** - stress on the first syllable.
**lazy** - stress on the first syllable.
**fishing** - stress on the first syllable.
So, **fishing** is the odd one out in terms of syllable number.

Continuing with the next set:
**vocation** - stress on the second syllable.
**balcony** - stress on the first syllable.
**average** - stress on the first syllable.
So, **vocation** is the odd one out in terms of syllable stress.

In the final set:
**glasses** - stress on the first syllable.
**describe** - stress on the second syllable.
**selfish** - stress on the first syllable.
So, **describe** is the odd one out in terms of stress position.

In summary:
1. **vegetable**
2. **fishing**
3. **vocation**
4. **describe**

These are the words that differ in pronunciation or syllable stress from the others.
