Final answer:
The invention of the microphone has allowed singers to be intimate with the audience.
Step-by-step explanation:
The statement, 'The invention of the microphone allowed singers to be intimate with the audience,' is true. Hand-held microphones, such as wireless body microphones, provide support to singers' voices and allow them to be heard clearly by the audience. In large venues or musical productions, microphones have become necessary to amplify the sound and ensure that the performance reaches all members of the audience. This invention has enabled singers to establish a more intimate connection with their audience, as their voices can be projected and heard clearly.
