Which of the words in the following sentence can be eliminated without changing the meaning the construction project downtown will be finished in approximately one year from now

Hello!

The sentence above is "The construction project downtown will be finished in approximately one year from now."

There are two words that can be removed without changing the meaning of the sentence: "from" and "now." 
Without these words, the sentence would become "The construction project downtown will be finished in approximately one year." This does not change the meaning of the sentence, because it still states that the project will be done in about one year. It does not need to be stated that the project will be finished one year 'from now.'

I hope this helps you!
