Which of the following most logically completes the argument?
United States manufacturers currently produce most of the world's solar-power generators—most of which are exported to Europe. However, European manufacturers are emerging and probably will ultimately capture much of the European market. The United States government is funding initiatives intended to encourage use of solar power within the United States. If these initiatives succeed in increasing the demand for solar-power generators in the United States, United States manufacturers will probably maintain significant production levels, since __________.
(E) the current market for solar-power generators in the United States is very limited
Let me explain why E is wrong.
Let me first start with a changed passage and a changed option E. Let's remove the "If part" of the last sentence of the passage and change option E as follows:
United States manufacturers currently produce most of the world's solar-power generators—most of which are exported to Europe. However, European manufacturers are emerging and probably will ultimately capture much of the European market. The United States government is funding initiatives intended to encourage use of solar power within the United States. United States manufacturers will probably maintain significant production levels, since __________.
E'. The current market for solar-power generators in the United States doesn't have much potential to grow.
What is the impact of the above option E'?
E' actually weakens the argument rather than strengthen it. If the current market doesn't have much potential to grow, the initiatives to encourage the use of solar power within the US may not succeed. As a result, US manufacturers may not be able to maintain significant production levels.

Now, let me reintroduce a
modified "if" part in the last statement of the passage:
United States manufacturers currently produce most of the world's solar-power generators—most of which are exported to Europe. However, European manufacturers are emerging and probably will ultimately capture much of the European market. The United States government is funding initiatives intended to encourage use of solar power within the United States. If these initiatives succeed in
significantly increasing the demand for solar-power generators in the United States, United States manufacturers will probably maintain significant production levels, since __________.
Now, what is the impact of option E' ?
Now, E' has no impact on the argument. Why? Because now, option E' just indicates that the "if" part is very unlikely to happen; E' doesn't impact the "if then" statement. Let me explain.
Let's say there is a statement "If you score 760 on the GMAT, you'll get into HBS."
Can you weaken this statement by saying that you're unlikely to score 760 on the GMAT?
No. Saying so will have no impact on the statement. The statement says that if X happens, Y will happen. What if X doesn't happen? That has no impact on the statement. The statement is weakened only if we say that even if X happens, Y may not happen.
Thus, E' will have no impact on this modified conclusion.

Now, let's talk about the original passage:
United States manufacturers currently produce most of the world's solar-power generators—most of which are exported to Europe. However, European manufacturers are emerging and probably will ultimately capture much of the European market. The United States government is funding initiatives intended to encourage use of solar power within the United States. If these initiatives succeed in increasing the demand for solar-power generators in the United States, United States manufacturers will probably maintain significant production levels, since __________.
E'. The current market for solar-power generators in the United States doesn't have much potential to grow.
In this case, we can argue that E' is a slight weakener since it limits the upside of the increase in demand for solar power generators in the US. We can argue that even if the initiatives succeed in increasing the demand for solar-power generators in the United States, the increase may not be substantial, and thus, US manufacturers may not be able to maintain significant production levels.

Now, let's talk about the original passage and the original option E.
United States manufacturers currently produce most of the world's solar-power generators—most of which are exported to Europe. However, European manufacturers are emerging and probably will ultimately capture much of the European market. The United States government is funding initiatives intended to encourage use of solar power within the United States. If these initiatives succeed in increasing the demand for solar-power generators in the United States, United States manufacturers will probably maintain significant production levels, since __________.
(E) the current market for solar-power generators in the United States is very limited
As we have discussed above, whether the current market for solar-power generators has the potential to grow substantially has an impact on the argument. However, option E says that the current market is very limited. The problem is that whether a market is very limited or not very limited, it may or may not have the potential to grow. Even if a market is not very limited, it may still have significant potential to grow. Thus, option E has no impact on the argument.
Rather, one may also think that this option has a slight negative impact since if the current market is very limited, growing it may also not be able to compensate for the loss of the European market.
