Step 3: Read the first sentence more carefully. Decide what information you will need. In this case, you will look for a section discussing inquiries about improving safety procedures.
Step 4: Once you have found the relevant section of the reading text, look back at the incomplete sentence and decide what specific information you need to complete it. In this case, you need to find what was initiated.
Step 5: Read that part of the text more carefully to find the answer. Remember that the correct answer you find in the text should fit the incomplete sentence grammatically. If not, you may need to look for another answer. In some IELTS tests the instructions will not say 'using words taken from the text', in which case you can use your own words or change the form of the words in the reading text.
