Answer:
En su nota, el periodista escribió que los nuevos datos presentados en su investigación demostraban que esa empresa había contaminado la zona durante años.
Explanation:
In this exercise you have to choose the sentence that changes from direct speech to indirect speech in the correct form. In this case, it is the second sentence.
The original sentence is: En su nota, el periodista escribió: "Los nuevos datos presentados en nuestra investigación demuestran que esta empresa ha contaminado la zona durante años". If you want to transform the sentence into indirect speech you have to change the verbs and the subject pronouns and possessives. In this case 'demuestran' changes to 'demostraban', 'nuestra' changes to 'su', 'esta empresa' changes for 'esa empresa' and 'ha contaminado' changes to 'había contaminado'.
