Answer: B
Supporting Sentence: During the day, when the home may not be using much electricity, excess power from the solar array is fed back to the grid, to factories and offices that need daytime power. This occurs in places like California in the US and Japan, where air-conditioning loads for offices and factories are large but heating loads for homes are small.
Keyword: day, electricity
Keyword Location: Section B, 4th Line
Explanation: As the supporting sentence is talking about the examples of countries like California in the US and Japan, where air-conditioning loads for offices and factories are large but heating loads for homes are small. The given information matches with Section B.
Answer: D
Supporting Sentence: This test station has allowed being explored in a systematic way, under well-controlled test conditions. With no insurmountable problems identified, the Japanese have used the experience gained from this station to begin their own massive residential photovoltaics campaign.
Keyword: photovoltaics, residential, country
Keyword Location: Section D, Last Line
Explanation: As from the supporting Sentence we can say that the description of the experiment is given in the Section D which matches with Information given in the statement. So, The given information matches Section D.
Answer: H
Supporting Sentence: For example, the use of photovoltaics or the equivalent may be stipulated to lessen demands on the grid network and hence reduce fossil fuel emissions.
Keyword: lessen demand, negative effect, conventional, grid network
Keyword Location: Section H, 2nd Line
Explanation: Fossil Fuel emission is the negative effect of using conventional means of generating electricity. Hence, Section H supports the information given in the statement.
Answer: B
Supporting Sentence: The photovoltaic-powered home remains connected to the power lines, but no storage is required on-site, only a box of electronics (the inverter) to the interface between the photovoltaics and the grid network.
Keyword: explanation
Keyword Location: Section B, 1st Line
Explanation: We can easily find the explanation of the photovoltaic system in Section B. As it talks about the details related to the technical aspects of it. It has been stated that the photovoltaics powered-home always stays connected to the power lines. There is no requirement of storage but only the electric box.
Answer: H
Supporting Sentence: It is likely that in the future, governments will develop building codes that attempt to constrain the energy demands of new housing.
Keyword: future, long ter
Keyword Location: Section H, 1st Line
Explanation: In the supporting sentence, we have written about the future scenario of the usage of photovoltaics which clearly matches with the information given in the statement with Section H.
Answer: E
Supporting Sentence: Meanwhile, Germany began a very important ‘1,000 roof program’ in 1990, aimed at installing photovoltaics on the roofs of 1,000 private homes. The success of this program stimulated other European countries to launch a similar program.

TRUE if the statement is true
FALSE if the statement is false
NOT GIVEN if the information is not given in the passage
(Guide: Candidates need to study the passage and identity the questions as true or false or not given)
Answer: FALSE
Supporting Sentence: The photovoltaics-powered home remains connected to the power lines, but no storage is required on-site, only a box of electronics (the inverter) to the interface between the photovoltaics and the grid network.
Keyword: Storage, electricity
Keyword Location: Section B, 1st Line
Explanation: During the day, when the home may not be using much electricity, excess power from the solar array is fed back to the grid, to factories and offices that need daytime power. At night, power flows the opposite way. So, from this we can say that Photovoltaics are not used to store electricity, these are used to remain connected to power lines. So, the statement is FALSE.
Answer: FALSE
Supporting Sentence: A change in US government priorities in the early 1980s halted this program.
Keyword: US government
Keyword Location: Section C, Last Line
Explanation: As the change in US government priorities in the early 1980s halted the photovoltaic program, the statement is false that the US government has provided continuous support for the use of photovoltaics on homes. So, the statement is FALSE.
Answer: TRUE
Supporting Sentence: A large residential test station was installed on Rokko Island beginning in 1986. This installation consists of 18 ‘dummy’ homes.
Keyword: uninhabited, dummy homes, Rokko Island
Keyword Location: Section D, 3rd Line
Explanation: As in Section C, there is written that the installation of the test station in Rokho consists of 18 ‘dummy’ homes which concludes that the houses were uninhabited. Hence, the statement is TRUE.
Answer: TRUE
Supporting Sentence: The program made a modest start in 1994 when 539 systems were installed with a government subsidy of 50 percent.
