The question is asking which sentence correctly uses an adjective ending in '-ial'. These adjectives are used to describe something relating to or characterized by a particular quality or feature. Let's analyze each option:
Option A: "The book is very industrial and easy to understand." - Here, 'industrial' is not used correctly as an adjective. 'Industrial' refers to something related to industry or manufacturing, so describing a book as industrial does not make sense in this context.
Option B: "The CEO's speech had a strong presidential tone." - In this sentence, 'presidential' is the adjective, and is correctly used. It describes the tone of the speech as similar to what you might expect from a president. The sentence implies that the speech carried qualities or characteristics related to a president, which makes sense and is contextually appropriate.
Option C: "This idea is very financial and clear." - The use of 'financial' as an adjective here is not correct. 'Financial' refers to something related to money or finance, but describing an idea simply as 'financial' without additional context does not clarify its meaning.
Therefore, the correct sentence using an '-ial' adjective in the appropriate context is option B: "The CEO's speech had a strong presidential tone."
Option B: "The CEO's speech had a strong presidential tone." is the correct choice as it uses the '-ial' adjective 'presidential' effectively in context, describing the speech's tone. Options A and C do not effectively clarify their adjectives within the context provided.
