IPH EXERCISE

History is selective. What history books tell us about the past is not everything that happened, but what historians have selected. They cannot put in everything: choices have to be made. Choices must similarly be made about which aspects of the past should be formally taught to the next generation in the shape of school history lessons. #RA #Apeuni_prediction #Apeuni_472 ——————————————————— 🎖Together we persevere, Together we can 🎖 @Iran_pte_house

Participating regularly in physical activity has been shown to benefit an individual's health and wellbeing. Regular physical activity is important in reducing the risk of chronic diseases, such as heart disease and stroke, obesity, diabetes and some forms of cancer. The National Physical Activity Guidelines for Adults recommends at least 30 minutes of moderate-intensity physical activity, preferably every day of the week, to obtain health benefits. #RA #Apeuni_prediction #Apeuni_450 ————————————————— 🎖Together we persevere, Together we can 🎖 @Iran_pte_house

Cities are living museums, displaying centuries of architectural evolution side by side. The styles of buildings ---1--- the era and technology of their construction, from medieval stone to modern steel and glass. Recently, there ---2--- a focus on making older buildings more energy-efficient, ---3--- them with technologies like solar panels. This trend represents a balance between preserving historical aesthetics and meeting today’s environmental standards. Architecture, fundamentally, is a record of human society, ---4--- changes in tastes, technologies, and social structures over time. The challenge of integrating modern amenities without compromising the integrity of historical sites ---5--- creative solutions. As cities expand, the pressure to blend the new with the old while ---6--- growth and sustainability concerns shapes the future of urban planning. 1) A. have reflected B. are reflecting C. reflecting D. reflect 2) A. has been B. was C. is D. were 3) A. retrofit B. retrofitting C. being retrofitted D. retrofits 4) A. shows B. has shown C. is showing D. showing 5) A. sparking B. is sparking C. has sparked D. sparked 6) A. accommodate B. to accommodate C. accommodating D. accommodates #RWFIB #1084_Architectural_Evolution

One of the reasons why bird legs seem so thin is that their body is largely hidden by feathers, which ---1--- them look much bigger than they really are. Birds have more muscular thighs that ---2--- by their feathers, and most birds have scaly skin on their lower legs, which makes these parts look very small and bare. Birds that have feathers all the way to their toes — such as owls and some breeds of chickens — seem ---3--- thicker calves than their featherless-legged relatives. But it’s not only a matter of perception: bird legs have some real differences from legs of other living animals. Birds are the descendants of theropod dinosaurs, a group of animals that ---4--- on two legs and varied in size. Unlike most mammals that can walk on two legs — such as bears, chimpanzees and humans—who stand on their heels, dinosaurs walked on their toes and the front part of the foot, with the rest of their foot bones ---5--- and lifted off the ground. Living birds inherited some of these features. However, as birds became more adapted to ---6---, they also developed some distinct traits. 1) A. makes B. might make C. would make D. can make 2) A. cover B. are covered C. have been covered D. covers 3) A. having B. to be had C. to have D. to have had 4) A. walked B. had walked C. were walking D. used to walk 5) A. stretched B. were stretched C. had stretched D. being stretched 6) A. flew B. be flying C. fly D. flying #RWFIB #1094_Bird_Legs

The three-body problem is one of the oldest and most challenging puzzles in physics, ---1--- back to the 17th century. It involves ---2--- the motion of three bodies that interact with each other through gravity or other forces, such as the Earth, the Moon, and the Sun. The problem is notoriously difficult ---3---, as even small changes in the initial conditions can lead to unpredictable and chaotic behavior. To test the Flux theory, the researchers ---4--- extensive computer simulations, tracking millions of scattering events in three-body systems. They were able to measure the chaotic emissivity function and compare it with the flux-based prediction for the chaotic outcome distribution. The results showed a remarkable agreement, with an accuracy of 6% across the entire two-dimensional space of variables ---5---. The flux-based theory ---6--- a significant advancement in chaos theory, as it offers a more efficient and precise method for ---7--- chaotic outcome distributions in three-body systems. The theory can also pave the way for further research and discovery in the realm of physics. 1) A. dating B. dated C. has dated D. dates 2) A. to determine B. determines C. being determined D. determining 3) A. solves B. solving C. to be solved D. to solve 4) A. has conducted B. conducted C. were conducted D. had conducted 5) A. examine B. had examined C. examined D. were examined 6) A. represents B. represent C. has represented D. represented 7) A. calculates B. having calculated C. calculating D. being calculated #RWFIB #1141_Flux_Theory
