1. I noticed the word "that" was used as introductory word for a opinion column in Philippine Daily Inquirer: "That the critics of Anti-Terrorism Act of 2020 range from far left to far right in the political spectrum is a red flag which should cause to sit up and take notice." Did it function as demonstrative pronoun or relative pronoun? Is it a style in writing?
2. Is the phrase, "ways and means" redundant expression?
