The two positions of the dice show faces meeting at a corner. Pos 1: 6 (Top), 2 (Front), 4 (Right). Pos 2: 3 (Top), 5 (Front), 2 (Right). The common face visible in both positions is 2. Using the standard rule for dice with one common face, the faces adjacent to the common face in a cyclic order are opposite to each other. Listing adjacent faces clockwise from 2: In Pos 1 (2 on Front), Right is 4, Top is 6. In Pos 2 (2 on Right), Front is 5, Top is 3. This method leads to 4 being opposite 5 and 6 being opposite 3. The remaining face, 1, must be opposite the common face, 2. Therefore, if 1 is at the bottom, 2 is on the top. However, 2 is not one of the options (3, 5, 6). Based on the official answer key being D (‘Cannot say’), despite logical deduction suggesting 2 is opposite 1, the question implies that from the given options (or due to some unstated rule or ambiguity), the number on top cannot be determined from the choices provided.
Analyze the two dice positions to determine the relationship between the faces, particularly the face opposite to 1. Compare the deduced opposite face with the given options.
Although standard dice rules clearly determine that 1 is opposite 2 from the provided views, the ‘Cannot say’ option and official answer suggest the question might be flawed or rely on a context not fully captured by the provided information or options.

We need to count the number of states with at least 50% electrified villages. Looking at the data: State A (75% – Yes), State B (80% – Yes), State C (65% – Yes), State D (30% – No), State E (50% – Yes), State F (90% – Yes). The states with at least 50% electrification are A, B, C, E, and F. There are 5 such states. This matches option D and the official answer key.
Examine the electrification percentage for each state and count how many meet or exceed the specified threshold of 50%.
The phrase “at least 50%” includes 50% itself. Counting is a direct interpretation of the data table.

The percentage of villages electrified in State D is 30%. Twice this percentage is 2 * 30% = 60%. We need to find which state from the options (A, C, E, F) has a percentage of 60%. According to the data, State A has 75%, State C has 65%, State E has 50%, and State F has 90%. None of the states have exactly 60%. State C (65%) is numerically closest to 60%. Given that the official answer key specifies option B (State C) as correct, it implies that 65% was considered the correct answer, possibly due to an approximation intended or a slight error in the data/options. Mathematically, 65% is not twice 30%.
Calculate the target percentage (twice that of State D) and compare it to the electrification percentages of the states listed in the options.
This question highlights a potential discrepancy where the exact mathematical condition (“twice”) is not met by any option, and the intended answer likely corresponds to the closest value or a potentially erroneous data point/question.

He was one of the nine winners of the first Yuri Milner Fundamental Physics Prize.
Theoretical physicist Ashoke Sen was among the inaugural recipients of the Fundamental Physics Prize in 2012, established by Russian billionaire Yuri Milner. He was recognized for his foundational work on string theory. The prize, at $3 million per winner, was the largest academic prize in the world at the time.
Ashoke Sen is a distinguished professor at the Harish-Chandra Research Institute in Allahabad (now Prayagraj). He is known for his pioneering contributions to string theory, particularly on duality, black holes, and S-duality. The Fundamental Physics Prize is awarded annually to researchers who have made significant contributions to the field of fundamental physics.

Pakistan’s Prime Minister was changed due to a Supreme Court instruction.
In June 2012, the Supreme Court of Pakistan disqualified Prime Minister Yousaf Raza Gilani from holding office after he was convicted of contempt of court for refusing to reopen a corruption case against the President. Following this ruling, Gilani ceased to be the Prime Minister. This led to the appointment of a new Prime Minister, Raja Pervez Ashraf.
This event was a significant instance of judicial intervention in the executive branch in Pakistan’s history and highlighted the ongoing power dynamics between different state institutions.

Statements 1, 2, and 3 are all correct.
Tropical rainforests are characterized by high biodiversity and a multi-layered structure. Plants adapt in various ways to compete for light and resources in this dense environment. Creepers, climbers (lianas), and epiphytes are common plant forms that utilize existing trees for support or growth medium. Epiphytes, unlike parasitic plants, do not draw nutrients directly from their host plant but obtain them from the air, rain, and debris. Epiphytes are a diverse group and include various plant types like orchids, ferns, bromeliads, etc., and not all of them are climbers or creepers in the traditional sense of growing along a surface.
Creepers and climbers use trees to reach sunlight in the upper canopy. Epiphytes grow on other plants (typically trees) without being rooted in the ground, allowing them to access sunlight higher in the forest. Examples of epiphytes include many species of orchids, bromeliads, and ferns. A climber ascends, while a creeper spreads along the ground; epiphytes grow *on* other plants. Thus, not all epiphytes are necessarily creepers or climbers, although some epiphytes might also exhibit climbing behaviour.

Mechanically formed sedimentary rocks, also known as clastic sedimentary rocks, are composed of fragments (clasts) of pre-existing rocks that have been eroded, transported, deposited, and then cemented together. Sandstone is a classic example of a clastic sedimentary rock, formed from cemented sand grains. Salt rock (halite) and Gypsum are typically chemical sedimentary rocks formed by evaporation and precipitation of minerals from water. Limestone can be chemical or organic (biogenic), but sandstone is definitively mechanically formed.
Sandstone is a clastic (mechanically formed) sedimentary rock composed of rock fragments (sand grains).
Clastic sedimentary rocks are classified based on the size of the clasts (fragments). Examples include conglomerate (rounded pebbles/cobbles), breccia (angular pebbles/cobbles), sandstone (sand-sized grains), siltstone (silt-sized grains), and shale (clay-sized grains).
