What's the difference between 表明 (biǎomíng) and 清楚地表明 (qīngchǔ dì biǎomíng)?

Question

A Jukuu.com example sentence:

图14．34清楚地表明了这一点。
Figure 14.34 illustrates this point rather nicely.
_{Tú 14.34 qīngchǔ dì biǎomíngle zhè yīdiǎn.}

Breaking this apart:

• 图14．34 (tú 14.34) = Figure 14.34
• 清楚 (qīngchǔ) = clear
• 地 (dì) = -ly (turning "clear" into the adverb "clearly")
• 表明 (biǎomíng) = to make clear
• 了 (le) = (past tense marker)
• 这 (zhè) = this
• 一点 (yīdiǎn) = a little

So maybe my translation would be "Figure 14.34 clearly makes clear this a little." However, the repetition of "clear" in 清楚地表明 seems strange.

Answer 2

表明 only means:

to make known, to state, to disclose

表明态度 for instance means to show ones attitude or state ones attitude.

It doesn’t necessarily mean that you did it in a clear way.

清楚地 means

clearly

oxford translates 清楚地表明 as:

clearly indicat(ed)

Or as a

clear signal
