關於英文something that started with a "D." 的問題。?

A:Renting a car "was" an awesome idea.
B:Yeah , we can see so much more this way.
A:I know the scenery is beautiful, but don't forget to look for our exit.
B:I "haven't seen" any signs since that orange one awhile ago.
A:What "did" it say?
B:I don't know , something that "started" with a D. But it "didn't look" important.

這段對話用了四次「過去簡單式」（發生或存在於過去的那個時間或空間裡），一次「現在完成式」（迄今為止仍有效的結果：過去發生或未發生），它們都是和過去的時空有關的事件。
他們談到「剛才」所看到的那個標誌，上面寫的字是以D開頭的。action verb的start是發生在「過去的」動作，所以用過去簡單式。

A: I "saw" a sign awhile ago.
B: What did "it" say?
A: It "said" something that "started" with a D. But it "didn't look" important.

The sign that I "saw" on the orange one "started" with a D, but it "didn't look" important.

這兩人開著車在找高速公路的出口，而出口標誌是橘黃色的。不久之前，A曾看到橘色標誌，但他不認為那是出口標誌，所以如此說。

Question: What did it say? 問題問: 你剛剛看到的橙色標誌上寫著什麼？

~ "it" refers to the orange sign which B just saw a while ago
~ "say" - to give written information or instructions

The question was asked in Simple Past Tense.
Therefore, the answer, as to what was written on the sign that B saw, should also be in simple past tense because of "verb tense consistency" concept.

Answer: I don't know, (but I "saw") something that "started" with a "D". ... 寫著的東西 首字母是"D"
"saw" and "started" are all past events.

The principle of Verb Tense Consistency:
~ Keep tenses consistent within sentences.
~ Do not change tenses when there is no time change for the action.
