What Each Text Contributes is a free printable Grade 5 English worksheet on identifying what one text supplies that another does not, aligned to Common Core standard RI.5.9. It prints 2 questions with an answer key on its own sheet of paper, in 25 versions, 23 of them with different questions, so no two pupils in the class work from the same page. Print it from the browser or download it as a PDF — no account, no email.

Why the Rails Are That Far Apart

Standard gauge is 4 feet 8½ inches. It is a strange number, and the reason is historical rather than engineering. Early railways were built by people who had built tramways for collieries, and those had used the wheel spacing of the carts already in use. Nobody chose it; it was inherited. Isambard Kingdom Brunel did choose. He built the Great Western at 7 feet ¼ inch, and by most measures it was better: faster, steadier, and able to carry more. He lost anyway. By the 1840s, more of the network was already standard gauge, and a train cannot run on a track it does not fit. Parliament settled it in 1846. Between 1846 and 1892 the Great Western converted its entire route. The final conversion took a single weekend and about four thousand men. The best design does not always win. The one that connects to everything else does.

Why the Thames Froze

Between 1309 and 1814 the Thames froze hard enough to walk on at least twenty-four times. Since 1814 it has not once. The usual explanation is that the climate has warmed. That is part of it, and not most of it. Old London Bridge had nineteen arches on wide stone piers. The piers took up so much of the channel that the bridge acted as a weir, slowing the water upstream almost to a standstill. Still water freezes; moving water does not. The river was also shallower and wider then, spreading over land that has since been embanked. Shallow water loses heat faster. Old London Bridge was demolished in 1831. The embankments were built between 1862 and 1874. The river that flows through London now is narrower, deeper and faster than the one that froze — and it would not freeze in a colder winter than any of those.

Answer key — What Each Text Contributes

Set 19. Prints on its own sheet.

  1. 1.1. Both show that reach and compatibility beat a technically better option. 2. This states its general conclusion outright; the canal text ends on an observation about holidaymakers.
  2. 2.1. This corrects a wrong explanation before giving the right ones; that one builds a mechanism forwards. 2. Both say the obvious explanation is not the main one.
