Final answer:
The incorrect sentence lacks a comma and should include 'of' in 'Performing in front of an audience, does not make her nervous'. The correct dialogue punctuation is in 'My mother said, “don’t touch that button!”'. 'Following no set pattern' describes an irregular fire alarm, '-ive' is the suffix for 'contemplate', and 'For this reason' is the suitable phrase for studies on a fly's brain.
Step-by-step explanation:
To answer the punctuation-related questions provided:
- The incorrectly punctuated sentence is: 'Performing in front an audience does not make her nervous'. It is missing a comma after the introductory phrase and should be 'Performing in front of an audience, does not make her nervous'.
- The sentence correctly punctuated with dialogue is: 'My mother said, “don’t touch that button!”'.
- The phrase that describes the fire alarm bell rang at irregular intervals is 'Following no set pattern'.
- The suffix to add to the word contemplate to make it an adjective is '-ive', resulting in 'contemplative'.
- Regarding the studies by scientists on a fly's brain, the appropriate phrase to use is 'For this reason'.
