How do I complete a block model by drawing the following geological structures on the plan view

(top) and all four sides of your block model:

● All map units are folded into an anticline with limbs dipping 30° towards the east and 30°

towards the west

● The anticline is cut by a right-lateral strike-slip fault that runs east-to-west and dips 70°

towards the north

Randomized controlled trials (RCTs) are the strongest research design for establishing cause and effect. Which of the following is the main limitation of RCTs?

a) RCTs may not be ethical for some studies.

b) RCT design cannot control for confounders.

c) Randomized controlled trials may have a disproportionate number of people exposed to the risk factor.

d) Randomized controlled trials are, by their very design, likely to be very biased towards an expected outcome.
