Input: Article: The apparently sudden appearance of nearly modern flowers in the fossil record initially posed such a problem for the theory of evolution that it was called an "abominable mystery" by Charles Darwin. However, the fossil record has considerably grown since the time of Darwin, and recently discovered angiosperm fossils such as Archaefructus, along with further discoveries of fossil gymnosperms, suggest how angiosperm characteristics may have been acquired in a series of steps. Several groups of extinct gymnosperms, in particular seed ferns, have been proposed as the ancestors of flowering plants, but there is no continuous fossil evidence showing exactly how flowers evolved. Some older fossils, such as the upper Triassic Sanmiguelia, have been suggested. Based on current evidence, some propose that the ancestors of the angiosperms diverged from an unknown group of gymnosperms in the Triassic period (245202 million years ago). Fossil angiosperm-like pollen from the Middle Triassic (247.2242.0 Ma) suggests an older date for their origin. A close relationship between angiosperms and gnetophytes, proposed on the basis of morphological evidence, has more recently been disputed on the basis of molecular evidence that suggest gnetophytes are instead more closely related to other gymnosperms.[citation needed]

Now answer this question: What relationship proposed on the basis of morphological evidence has recently been disputed?

Output: relationship between angiosperms and gnetophytes

Input: Article: Zhejiang is the home of Yueju (), one of the most prominent forms of Chinese opera. Yueju originated in Shengzhou and is traditionally performed by actresses only, in both male and female roles. Other important opera traditions include Yongju (of Ningbo), Shaoju (of Shaoxing), Ouju (of Wenzhou), Wuju (of Jinhua), Taizhou Luantan (of Taizhou) and Zhuji Luantan (of Zhuji).

Now answer this question: Who is Yueju traditionally performed by?

Output: actresses only

Input: Article: Incandescent bulbs have been replaced in many applications by other types of electric light, such as fluorescent lamps, compact fluorescent lamps (CFL), cold cathode fluorescent lamps (CCFL), high-intensity discharge lamps, and light-emitting diode lamps (LED). Some jurisdictions, such as the European Union, China, Canada and United States, are in the process of phasing out the use of incandescent light bulbs while others, including Colombia, Mexico, Cuba, Argentina, Brazil and Australia, have prohibited them already.

Now answer this question: What does the acronym CFL refer to?

Output:
compact fluorescent lamps
