    Design a text processing function for an adaptive learning system that removes emphasized (uppercase) segments from student responses to standardize their input for assessment. The function should preserve all lowercase text while eliminating any uppercase character sequences, maintaining the original spacing and punctuation. The cleaned text will be used for automated analysis of student comprehension, focusing solely on core content rather than stylistic emphasis.
