Ein muskulös_ Mann (m.) geht da.
Explanation
The given sentence "Ein muskulöser Mann geht da." is in German and it means "A muscular man is going there." In German, adjectives have to agree with the gender and case of the noun they modify. In this case, "muskulöser" is the masculine singular form of the adjective "muskulös" because it is modifying the masculine noun "Mann". The ending "-er" is used for masculine singular nominative adjectives. Therefore, the correct answer is "-er".
2.
Ich gehe immer mit einer blau_ Tasche (f.).
Explanation
The correct answer is "-en" because it is the correct ending for the adjective "blau" when used with a feminine noun in the accusative case. In German, adjectives need to agree in gender, number, and case with the noun they modify. In this case, since the noun "Tasche" is feminine and in the accusative case, the adjective "blau" takes the ending "-en".
3.
Die Kleidung des attraktiv_ Mädchens (n.) ist sehr schön.
Explanation
In this sentence, the adjective "attraktiv" is describing the noun "Mädchen". Since "Mädchen" is a neuter noun, the adjective ending should be "-en" in the nominative case. Therefore, the correct form of the adjective is "attraktiv_en".

Es tut meinem verletz_ Arm (m.) weh.
Explanation
Wehtun is a dative verb, so the noun and adjective ending become dative.
5.
Ich liebe hübsch_ Katzen (p.).
Explanation
The correct answer is "-e" because in German, when using the adjective "hübsch" (meaning "pretty" or "beautiful") to describe plural nouns, the adjective takes the ending "-e". Therefore, to correctly say "I love pretty cats" in German, we would say "Ich liebe hübsche Katzen."
6.
Der rot_ Ball (m.) ist mein.
Explanation
The correct answer is "-e" because in German, when a masculine noun is in the nominative case and singular form, and is preceded by the definite article "der", it takes the ending "-e" in the possessive form. Therefore, "Der rot_ Ball (m.) ist mein" translates to "The red ball is mine."
7.
Ich gehe an die grün_ Tafel (f.).
Explanation
The given correct answer is "-e" because in German, when a feminine noun ends in -e in the nominative case, it does not undergo any changes in the accusative case. Therefore, the correct form of the adjective "grün" remains the same in the accusative case when used with the feminine noun "Tafel".
8.
Ich finde die jung_ Mädchen (p.) ärgerlich.
Explanation
The correct answer is "-en" because in this sentence, "jung" is an adjective modifying the noun "Mädchen" which is plural. In German, when an adjective is used to describe a plural noun, it takes the ending "-en".
9.
Ich gebe böse_ Feinden (p.) eine Flasche Gift.
Explanation
The correct answer is "-n" because in German, when a plural noun is in the accusative case and preceded by a masculine or neuter article, it takes the "-n" ending. In this sentence, "Feinden" is a plural noun in the accusative case, and it is preceded by the masculine article "böse". Therefore, it requires the "-n" ending.
10.
Ich gehe gern durch den groß_ Wald (m.).
Explanation
The correct answer is "-en" because the word "groß" is in the accusative case and the noun "Wald" is a masculine noun. In the accusative case, masculine nouns take the ending "-en" when there is no article or determiner preceding it. Therefore, "durch den groß_ Wald" is the correct form.
