Not able to apply math strategy

Please tell how to apply math strategy in this question, and how to predict answer.

Although Father’s Day, first celebrated in 1908, is now an honored tradition in the United States, it did not always enjoy such __________; rather, unofficial __________ from prominent figures such as Woodrow Wilson and William Jennings Bryan were required before Americans embraced the holiday.

i think the both blanks have similar connotation… and can be filled with ‘celebration’. What choices do we have?

Isn’t rather will change tone ?

Before the first blank, we can see “not”
not enjoy such ____ , rather enjoy ______
not enjoy and enjoy are already a contrast with rather.
