-China's secretive space plane has recently performed a dramatic manoeuvre in low Earth orbit, dropping from an altitude of 375 miles to 365 miles in the span of roughly a day earlier this month. ( 1 ) The robotic spacecraft - in essence, a quarter-length Space Shuttle - has been in space since December 14, zipping around Earth at different altitudes and even releasing at least one object: potentially a tiny satellite, a now-useless piece of its launch hardware or, alternatively, a target for practice manoeuvres. ( 2 ) It would make sense that it's a target. ( 3 ) The space plane, China's answer to the US Air Force's own Boeing X-37B space plane, is widely assumed to have inspection capabilities. ( 4 ) That is, it can manoeuvre close to other spacecraft in order to inspect them - or, in wartime, tamper with them, possibly even destroying them. With its apparent wartime role, the Chinese space plane is just one of several "dual-use" spacecraft - with civilian and military applications - in orbit right now. ( 5 ) On May 16, Russia launched an apparent inspection satellite designated Cosmos 2576. Four days later, Ambassador Robert Wood, the US alternate representative for special political affairs in the United Nations, claimed Cosmos 2576 is "likely a counter-space weapon, presumably capable of attacking other satellites in low Earth orbit."

The most suitable location for the sentence "The excavations were part of a project to learn more about how people first dispersed from mainland Asia, through the Indonesian archipelago and into the prehistoric continent that once connected Australia and New Guinea." is before sentence (4).

-In early April 2019, Dr. Ceri Shipton and his colleagues from the Australian National University became the first archaeologists to explore Obi, one of many tropical islands in Indonesia's Maluku Utara province. ( 1 ) The research team's discoveries suggest that the prehistoric people who lived on Obi were adept on both land and sea, hunting in the dense rainforest, foraging on the seashore, and possibly even voyaging between islands. ( 2 ) The team's earlier research suggested that the northernmost islands in the group, known as the Wallacean islands, including Obi, would have offered the easiest migration route. ( 3 ) It also seemed likely that these islands were crucial "stepping stones" on humans' island-hopping voyages through this region millennia ago. ( 4 ) The excavations were part of a project to learn more about how people first dispersed from mainland Asia, through the Indonesian archipelago and into the prehistoric continent that once connected Australia and New Guinea. But to support this idea, they needed archaeological evidence of humans living in this remote area in the ancient past. So, they travelled to Obi to look for sites that might reveal evidence of early occupation. ( 5 ) Just inland from the village of Kelo on Obi's northern coast, Shipton and his colleagues found two caves containing prehistoric rock shelters that were suitable for excavation. With the permission and help of the local people of Kelo, they dug a small test excavation in each shelter.

The most suitable location for the sentence "The type of ledger favoured by the crypto industry, these blockchains can be accessed by any computer running the necessary software to host them, with no identification or vetting required." is before sentence (4).

-Traditional financial institutions are increasingly showing interest in "tokenising" real-world assets, meaning they are curious about how these assets could be digitally represented by programmable tokens recorded on shared ledgers. ( 1 ) There could be real efficiency gains associated with tokenisation, but the drive towards it could also take a dark turn. ( 2 ) The most dangerous outcomes would arise if the tokenisation of real-world assets were pursued simply to feed into what has been described as "the perpetual motion machine that is crypto trading". ( 3 ) Regulators around the world have expressed concerns about the integration of crypto and traditional financial markets, because of the high levels of volatility, leverage, concentration and operational risk associated with the crypto markets. The type of ledger favoured by the crypto industry, these blockchains can be accessed by any computer running the necessary software to host them, with no identification or vetting required. ( 4 ) This integration would be sped up if ownership of tokenised real-world assets were recorded on so-called permissionless public blockchains. The tokenisation of real-world assets can and should proceed without using these problematic blockchains. ( 5 ) Their inefficiencies are well-documented, and experimentation to resolve problems in scaling their use tends to focus on processing transactions of the blockchain.
