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