Translate into Latin: 'When you have read the book, you will see.'

The correct answer is a suitable choice for translating the phrase "When you have read the book, you will see" into Latin due to the use of the conjunction "ubi" (meaning "when"), along with the appropriate tense and mood in the verb forms.

In Latin, the perfect tense (legisti) is used to indicate a completed action, translating effectively to "you have read." The use of the subjunctive mood "legeris" in this choice correctly reflects the conditionality often present in such phrases. The combination of "ubi" and "cum" (though in this context "ubi" alone suffices) adds clarity to the timing of the action.

Additionally, this structure elegantly communicates the idea that once the action of reading is completed, the subsequent action of seeing will occur.

The other choices present various issues: some use the imperfect or other forms that do not accurately capture the intended meaning or grammatical structure needed for proper translation in this context.
