In the question below, two statements are given with one blank each, which must be filled in with the same word. Following the statements are five words. Choose the most appropriate word which could fill in both the blanks to make both the statements grammatically and contextually correct.
I. The new regulation will ________ banks from engaging in speculative lending activities.
II. Parents are advised to ________ children from spending excessive time on social media platforms.

The correct answer is Prevent.

To determine the correct word that fits both blanks, let's analyze the grammatical structure and context of both statements:

Statement I: "The new regulation will ________ banks from engaging in speculative lending activities."
Here, the modal verb "will" must be followed by a base verb. The blank is followed by the structure "[object] + from + verb-ing" ("banks from engaging"). The verb "prevent" perfectly fits this structure ("prevent someone from doing something") and contextually means to stop the banks from participating in risky lending behaviors.

Statement II: "Parents are advised to ________ children from spending excessive time on social media platforms."
In this sentence, the infinitive particle "to" must be followed by a base verb. Similar to the first statement, we have the structure "[object] + from + verb-ing" ("children from spending"). The verb "prevent" fits both grammatically and contextually, meaning to stop or hinder children from spending too much time on these platforms.

Let's evaluate the other options:
- Procure: Means to obtain or secure something, which does not make sense in either context.
- Dominate: Means to control or rule over, which does not grammatically collocate with the preposition "from" in this context.
- Restricts: This is a third-person singular verb. It is grammatically incorrect because both sentences require the base form of the verb after "will" and "to" (which would be "restrict").
- Discourage: While it fits the sentence structure, "Prevent" is the chosen most appropriate word to express stopping these actions completely.
