1. We are studying the properties and strength characteristic of various types of clays. The ratio of the unconfined com- pressive strength of an undisturbed sample to that of a remolded one at the same water content and porosity defines the clay’s:
a) Activity ratio. b) Sensitivity. c) Ultimate strength. d) Ductility.
e) Mad geotechnical scientists says: I like the unconfined compression test because I can squeeze the living day- lights out of a sample and watch it get short and fat and break and squash and flow and burst and ooze and….

2. In exploration geophysics, seismic inversion refers to: a) Seismic processing steps to attenuate the presence of “diffractions.” b) The combined processes of “demultiplex” and “muting.” c) Transforming seismic reflection data into quantitative rock properties. d) Eliminating or minimizing the occurrence of multiples from the seismic record. e) Analyzing and interpreting seismic sections while standing on your head.
