Final answer:
To turn the statement 'La profesora Cruz prepara la prueba' into a question, you should invert the subject and the verb to form the question '¿Prepara la profesora Cruz la prueba?'. This structure applies to question formation by word order inversion in Spanish.
Step-by-step explanation:
To convert the given sentence 'La profesora Cruz prepara la prueba' into a question by inverting the word order, you should place the verb before the subject. The sentence becomes: '¿Prepara la profesora Cruz la prueba?' This follows the correct structure for formulating questions in Spanish.
The general rule for creating questions from statements in Spanish is to invert the order of the subject and the verb. In English, we often use auxiliary verbs or a change in intonation to form questions, but in Spanish, inversion is a common method. Additionally, Spanish questions typically start with an inverted question mark ('¿') and end with a regular question mark ('?').
Including question words such as qué, quién, cuándo, dónde, etc., can provide more specificity to the question, but are not necessary for simple subject-verb inversions.
