Make the following paragraph easier to understand

To make the paragraph easier to be understood, you can employ the following techniques:
1. Spot and remove adjectives or adverbs that do not deliver real meanings
2. Use active voice rather than passive voice
3. Replace long definitions with words that encapsulate the same meaning

Synthetic cubism is __much more energetic__ (Much more energetic than what? If this is a stand alone paragraph, "much more" would be prime candidates for elimination), and often makes use of collage, __normally playing cards or musical notation paper__ (Does the reader care what type of collage is being used?). __This type of cubism was developed by Picasso__ (passive voice sentence; note that the subject is also the same as in the previous sentence). __During the two artists' time of collaboration from 1907 and ending with the First World War__(Does the phrase not essentially say that the two artists collaborated from 1907 to the end of the First World War?), their styles intermingled and they painted the same subjects, making their works __at times closely resemble each other__ (Does this not simply mean "similar?").

After the above analysis, you may come up with the following:

Synthetic cubism, developed by Picasso, is energetic and often makes use of collage using playing cards or musical notation paper. When the two artists collaborated from 1907 until the end the First World War, their styles intermingled and they painted the same subjects, making their works of close resemblance at times.

Synthetic cubism is an energetic collage using playing-cards or musical notation papers , which was developed by Picasso. During their collaboration between 1907 and the end of World War I , the two artists painted the same subjects, thereby producing the closely resemble art works .
