Meaning: 'Offer' means to present or provide something for someone to accept or use, in this case, a chance for students.

Wrong options:

• resemble: 'Resemble' means to look like or be similar to something, which does not fit the context of providing an opportunity.
• stow: 'Stow' means to pack or store something away, which is unrelated to the purpose of fieldwork.
• rave: 'Rave' means to talk wildly or enthusiastically, which does not convey the intended meaning of providing an opportunity.

Correct answer: apply

Explanation: The word 'apply' is the correct verb that indicates putting knowledge into practice, which fits the context of students using what they have learned. It matches the grammatical structure required after 'to' as an infinitive form.

Meaning: 'Apply' means to use knowledge or skills in a practical situation, which is the goal of fieldwork for students.

Wrong options:

• compare: 'Compare' means to examine the similarities and differences, which does not fit the context of using knowledge practically.
• align: 'Align' means to arrange in a straight line or to be in agreement, which does not convey the action of using learned knowledge.
• dismount: 'Dismount' means to get off or down from something, which is irrelevant to the context of applying knowledge.

Correct answer: have

Explanation: The word 'have' is the correct form of the verb that indicates possession in the present perfect tense, which is appropriate here as it refers to what students currently possess in terms of knowledge learned.

Meaning: 'Have' indicates possession or ownership, meaning students currently possess the knowledge they have learned.

Wrong options:

• has: 'Has' is the singular form of the verb and does not agree with the plural subject 'students.'
• had: 'Had' is the past tense form, which does not fit as the context refers to current learning.
• been: 'Been' is a past participle that does not function as a main verb in this context.

Correct answer: obtained

Explanation: The word 'obtained' is the correct past participle that fits the passive construction of the sentence, indicating that experience cannot be acquired from books. It aligns grammatically and contextually with the phrase 'cannot be.'

Meaning: 'Obtained' means to get or acquire something, in this case, experience that is not gained from books.

Wrong options:

• originated: 'Originated' means to begin or arise from something, which does not fit the context of acquiring experience.
• prepared: 'Prepared' means to make ready, which does not convey the idea of acquiring experience.
• touted: 'Touted' means to promote or praise something, which does not fit the context of gaining experience.
