When asking a comparative question in Japanese, the two items being compared are listed first, each accompanied by the particle to ("and"). Following this is the interrogative pronoun dochira ("which of the two") followed by the subject marker ga and, finally, an adjective, the copula desu and the question marker ka. To answer a comparative question, simply state the answer, followed up with the phrase no hō ga along with the proper adjective.
The particle of yo at the end of a sentence is used to indicate the speaker's strong conviction. When expressing conjecture, ("is probably,"), deshō can be used in place of desu at the end of the sentence.
NOTE: Dotchi is the colloquial form of dochira (example. 3)
Kono himo to sono himo to, dochira ga tsuyoi desu ka.
Which is stronger, this cord or that cord?
Sono himo no hō ga tsuyoi deshō.
This cord is stronger, I guess.
O-tō-san to o-kā-san to, dochira ga kibishikatta desu ka.
Who was stricter, your father or your mother?
Haha no hō ga kibishikatta desu.
My mother was stricter.
Chikatetsu to basu to, dotchi ga benri desu ka.
Which is more convenient, the subway, or the bus?
Chikatetsu no hō ga benri desu yo.
The subway is more convenient, by far.
Hope this helps!
