To study the effect of different types of stimuli on memory recall, Zhong subjects participants divided into two equivalent groups to either an auditory or a visual presentation of a poem. After the presentation, the participants are asked to answer several questions about the poem. Which type of experimental design has Zhong employed?

Svetlana wants to know if a new sports drink improves physical performance. The number of push-ups each participant can complete in 1 minute is recorded first. The participants are then given 8 ounces of the sports drink, and the number of push-ups completed in 1 minute is recorded again. Svetlana finds that the number of push-ups completed is less after consuming the new sports drink. This finding is likely the result of a________ effect.

Caleb placed $5,500 in three investments that pay an annual interest of 4%, 5% and 7%. He placed twice as much money in the 7% investment as he did in the 4% investment. His total interest for the year is $320. Using a 3×3 system, determine the amount of money Caleb placed in each of the three investments. Given x = the investment at 4%, y = the investment at 5%, and z = the investment at 7%, give the answer in the format (x, y, z) if there is a solution and `no solution` if it cannot be solved. (space between `,` and `#`)
