Since turbines are designed without a(n) (i)____ understanding of such wind flows, they are failing at higher than expected rates. Failure to anticipate sudden gusts is especially (ii)____, because they can both damage the turbines and lead to sudden transmission line overloads. The situation is similar to the early days of aviation, when aircraft designers were working by (iii)____ because the atmosphere was so poorly understood.
Kudos for the right answer and solution.
| Blank (i) | Blank (ii) | Blank (iii) |

| dubious | problematic | sophisticated design |

The sentence fragment "they are failing at higher than expected rates" suggests that the turbines were designed with improper or incomplete or wrong understanding of (such) wind flows. But the word "without" in front of the blank necessitates a positive word. Clearly complete is the only option.
Since sudden gusts can both damage the turbines and lead to sudden transmission line overloads, the failure to anticipate them is problematic. If the failure to anticipate was elusive or intriguing it would not have had a well-defined consequence.
We are told that in the early days of aviation the atmosphere was poorly understood. And the current situation where the wind flows are poorly understood and gusts of wind are unanticipated is compared to the early days of aviation. This makes it clear that the aircraft designers were working not by sophisticated design or proven routine, but by trial and error.

1. The first blank can be filled discretely. The clause "they are failing at higher than expected rates" suggests that the first blank after the negative word "without" should be positive in tone. Only "complete" fits here.
2. The second blank should explain "can both damage the turbines and lead to sudden transmission line overloads" - hence, only "problematic" suits here.
3. The third sentences mentions the parallel analogy and hence should follow the turbine context - no complete understanding. Only "trial and error" fits here
