Explanation:
An adjective is a word that is used instead of a noun that describes what can be sensed or seen.
The word "appalling" in the first sentence is an adjective that is used to describe the state of the kitchen.
In the third sentence, the words "miniskirt" and "beige tweed" are adjectives that are used to describe the type of skirt and color.
An adverb is a word that is used to modify a verb by giving more information about the verb.
In the second sentence, the word "loudly" is an adverb that is used to show how loudly his father belched after the meal.
A simile is a phrase that uses "like" or "as" to compare two things to make the description more emphatic.
In the fourth sentence, "...as white as Mary in the manger" is a simile to compare how pale he was.
