Task: d53ff5ee-3b1a-431e-b2be-30ed2673079b

#### 重要信息 - LibreOffice Writer is open with a document called "presentation_instruction_2023_Feb.docx" - The document contains uppercase text sections: - "CHIN9505" (course code in uppercase) - A large block starting with "PREPARE A PRESENTATION ABOUT 2-3 MINUTES..." which is entirely in uppercase - The paragraph continues with "YOU NEED TO TALK IN THE FRONT OF THE CLASSROOM..." and more all-caps text - The strategy tree indicates I need to convert these uppercase sections to lowercase - According to the key visual evidence, the expected outcome shows both 'CHIN9505' and the instruction block converted to lowercase #### 情况分析与思考过程 The task is to convert all uppercase text to lowercase. I can see there's a significant block of text in all caps that needs conversion. The best approach is: 1. First, I'll select the all-caps paragraph block (starting with "PREPARE A PRESENTATION...") 2. Use Format > Text > lowercase to convert it 3. Then handle the "CHIN9505" course code 4. Save the document I'll start by clicking at the beginning of the uppercase block and dragging to select it. I can see "PREPARE A PRESENTATION" starts around the middle of the page. Let me select this entire uppercase block by clicking and dragging from the beginning of "PREPARE" to the end of the uppercase section (which appears to end with "fluency." or thereabouts). Looking at the document, I need to select the all-caps text block. I'll triple-click to select a paragraph or click and drag to select the specific uppercase section. Let me click at the start of "PREPARE" and drag to select the entire uppercase instruction block.
