Scarcely (adverb) di depan kalimat pada inverted word order sih Rizki. Pada word order normal, scarcely biasanya setelah main verb “be”, sebelum main verb (biasa / bukan “be”), atau setelah auxiliary verb .

I was scarcely able to move my arm after the accident. (setelah main verb “was”)
…
I scarcely heard him laugh all night. (sebelum main verb “heard”)
The city centre has scarcely changed in over a century. (setelah auxiliary verb “has”) https://dictionary.cambridge.org/dictionary/english/scarcely

Semoga membantu Rizki 🙂

Bolehkah saya minta contohnya,supaya lebih jelas?

Mae West — ‘You only live once, but if you do it right, once is enough.’

but bekerja untuk semua clause yang di bold, if untuk clause “you do it right” dan “once is enough”.

mungkin bisa saja Suhendi jika mereka “bekerja” dengan clause yang berbeda

Halo Elmerfiqi,

Menurut cambridge, either (or)

used when referring to a ​choice between two ​possibilities…

We can either ​eat now or after the show – it’s up to you.
Either you ​leave now or I ​call the ​police!
http://dictionary.cambridge.org/dictionary/english/either

sedangkan whether (or)

(used to ​introduce two or more ​possibilities) it is not ​important if:

I’m going, whether she ​likes it or not.
Someone has to ​tell her, whether it’s you or me. http://dictionary.cambridge.org/dictionary/english/whether

Dari situ saya lihat either dan whether sama-sama membicarkan two possibilities tapi either lebih netral sedangkan whether ada penekanan it is not ​important if. Mungkin kamu bisa cek sumber lainnya, siapa tau ada yang menyatakan interchangeable.

Iya Chavez..memang diantara as…as itu tinggal isi adjective atau adverb aja 🙂
