Final answer:
In the context of the provided sentences, the adjectives 'Italian' and 'Polish' should be capitalized because they are proper adjectives derived from proper nouns and represent the name of a country or culture.
Step-by-step explanation:
The student's question is related to the correct use of capital letters in the context of adjectives derived from proper nouns. When an adjective derives from a proper noun, such as the name of a country, city, or culture, it should be capitalized because it is considered a proper adjective. This is in accordance with the components of Mechanics H 10 in writing.
Looking at the italicized adjectives provided in the student's examples:
- We cooked smoked sausage on the barbecue.
- Italian hot sausage sandwiches. (The adjective 'Italian' derives from the proper noun 'Italy' and therefore should be capitalized.)
- They served slices of summer sausage.
- What gives Polish sausages their distinctive flavor? (The adjective 'Polish' derives from the proper noun 'Poland' and therefore should be capitalized.)
Therefore, the italicized adjectives that should be written with a capital letter are 'Italian' and 'Polish'.
