Answer:
The words "refused to" and "held up" convey a disapproving tone.
Explanation:
The words "refused to" and "held up" imply a tone of disapproval over the pipeline that needed to pass under a branch of the Pennsylvania Railroad. These words show that this pipeline was rejected because there was a disapproval in its implementation over the branch of the railroad. In short, the words indicate that something is being rejected which implies a tone of disapproval in the excerpt.
