[EX Q]: Passage: Although the reciprocating steam engine is no longer in widespread commercial use, various companies are exploring or exploiting the potential of the engine as an alternative to internal combustion engines. The company Energiprojekt AB in Sweden has made progress in using modern materials for harnessing the power of steam. The efficiency of Energiprojekt's steam engine reaches some 27-30% on high-pressure engines. It is a single-step, 5-cylinder engine (no compound) with superheated steam and consumes approx. 4 kg (8.8 lb) of steam per kWh.[not in citation given] Question: Where is Energiprojekt AB based?
[EX A]: Sweden

[EX Q]: Passage: There are some common misconceptions about the outer and inner chloroplast membranes. The fact that chloroplasts are surrounded by a double membrane is often cited as evidence that they are the descendants of endosymbiotic cyanobacteria. This is often interpreted as meaning the outer chloroplast membrane is the product of the host's cell membrane infolding to form a vesicle to surround the ancestral cyanobacterium—which is not true—both chloroplast membranes are homologous to the cyanobacterium's original double membranes. Question: How do both chloroplast membranes compare to cyanobacterium's original double membranes?
[EX A]: homologous

[EX Q]: Passage: In the final years of the apartheid era, parents at white government schools were given the option to convert to a 'semi-private' form called Model C, and many of these schools changed their admissions policies to accept children of other races. Following the transition to democracy, the legal form of 'Model C' was abolished, however, the term continues to be used to describe government schools formerly reserved for white children.. These schools tend to produce better academic results than government schools formerly reserved for other race groups . Former 'Model C' schools are not private schools, as they are state-controlled. All schools in South Africa (including both independent schools and public schools) have the right to set compulsory school fees, and formerly model C schools tend to set much higher school fees than other public schools. Question: How do the fees at former Model C schools compare to those at other schools?
[EX A]:
much higher
