Certainly, let's go through each option and explain why or why not it provides support for the reasoning in the argument:
(A) "The cost of starting a space project increases every year."
This option discusses the rising costs of starting space projects but doesn't directly address the argument's premise that large projects should be abandoned in favor of small ones due to recent setbacks and financial losses. It's more about cost trends than the feasibility or advantages of small projects.
(B) "It is just as easy to revise, and even scrap, small projects as it is large ones."
Option (B) supports the argument by suggesting that small projects are as flexible and easy to manage as large ones. This implies that if setbacks occur or if adjustments are needed, it is just as feasible to revise or abandon small projects. This supports the idea that small projects might be a better choice given recent difficulties with large projects.
(C) "Large projects are intrinsically more likely to fail and so are more financially risky than small projects."
Option (C) directly supports the argument. It states that large projects are more likely to fail and are financially riskier than small projects. This information reinforces the argument's premise that due to the setbacks and financial losses, it makes sense to abandon large projects in favor of smaller, less risky ones.(D) "Project managers prefer to work on small projects rather than large ones."
This option talks about the preferences of project managers but doesn't provide direct support for the argument's reasoning regarding setbacks and financial losses of large projects.
(E) "Large space projects can explore a few places thoroughly, while small projects can investigate more regions, though less thoroughly."
Option (E) provides information about the capabilities of large and small projects but doesn't directly address the financial or managerial aspects that support the argument. It discusses the trade-off between depth and breadth of exploration but doesn't relate to the argument's main points.
So, upon further examination, option (C) is indeed the option that provides the most direct support for the argument's reasoning. It highlights the intrinsic risk associated with large projects, which aligns with the argument's assertion that large projects should be abandoned in favor of smaller ones due to setbacks and financial losses.
