Difficulty: MediumPlural and Possessive Nouns and Pronouns

Complete the passage below by typing the grammatically correct form of the noun 'horse' in the blank.

Answer:During the late nineteenth century, British photographer Eadweard Muybridge captured pioneering sequential images of animals in motion. By utilizing a complex series of custom-built cameras triggered by tripwires, Muybridge was able to freeze a running 【horse's】 strides in a way that had never been seen before, conclusively proving that all four of the animal's hooves leave the ground simultaneously during a gallop.

Answer

horse's
The sentence requires the singular possessive form of the noun 'horse' because the indefinite article 'a' specifies a single animal, and the noun 'strides' that follows requires a possessive modifier.

Step-by-Step Solution

1
Analyze the grammatical context surrounding the blank to determine if the noun should be singular or plural.
The blank is preceded by the singular indefinite article 'a' ('a running...'), which indicates that a singular noun is required.
The article 'a' must modify a singular noun phrase.
2
Determine if the noun needs to be possessive or non-possessive.
The blank is followed directly by the noun 'strides' ('...strides in a way...'), indicating that the noun in the blank must possess the strides. Therefore, a possessive form is required.
A noun modifying another noun to show ownership or association requires the possessive case.
3
Combine singular number and possessive case to form the correct word.
The singular possessive form of the noun 'horse' is 'horse's'.
Singular possessive nouns are formed by adding an apostrophe and an 's' to the singular noun.
