Answer:
1. She should capitalize "two" because it is an adjective.
Step-by-step explanation:
The above is the change that would be correct. In capitalization of titles, it is important to note that the first and last words of the title should be capitalized. Also, all nouns, pronouns, adjectives, verbs, and adverbs should be capitalized. Articles (a, an, the), prepositions and coordinating conjunctions should be lowercased.
When "two" is used to modify a noun/noun phrases or pronouns, they act as adjectives. The "two" should be capitalized because it is an adjective, modifying the noun "Paths".
