EU referendum, brexit and the aftermath

Although they are the answers on the actual version the tweet seems to miss the bit where it says "See p. x for further information" which does give a more detailed answer.

For instance, the answer to Q 18 is actually
No.
FDI (foreign-owned capital seeking to invest here or elsewhere) goes where there are good returns.
The UK has always been a magnet for FDI because of its strong legal framework and generally probusiness
climate. Although there possibly could be an initial hiatus - largely due to perceived
uncertainty - it is instructive to observe that inward investment has continued to be strong following
the Referendum and despite an unparalleled campaign of fear that continues to this day.
Once it is clear that the UK is moving to a system of free trade through a combination of FTAs with
robust protections for foreign investors and unilateral tariff reductions, accompanied by less
onerous regulations, FDI is likely to surge. Singapore operates a free trade policy and FDI has
always been strong.
What could change after Brexit is the perception of the sectors where returns are perceived by
investors to be most attractive.
