"The fork and the spoon"

Translation: Ke ʻō a me ke puna

[rabelon]

By Wehewehe.org, "ke puna" is the correct use of the article. The word for fork, ‘ō begins with an okina, not an "o." The proper article for this word is "ka," as in "ka ‘ō." I believe DL got this one reversed, which is unfortunate. Imagine trying to learn English with the sentence "a egg and an bird."
I wrote "Ke puna a me ka ‘ō" and was marked incorrect.

Per DL, spoon/puna takes "ke" (dictionary verifies this) but here itʻs "ka". (Ka puna is spring of water). Edit: Duo is now using ke for puna. 3/3/19

why is it ke puna and not ka puna?

[MacKinzieRob]

Pukui, Elbert Mo'okini: "Ke precedes nouns beginning with a-, e-, o-, and k-, and before some nouns beginning with the glottal stop and p-, ka occurs elsewhere....."
