filosofia para » filosofia da, filosofia morale
during studie » during studies, during study, during soldier
tests during » costs during, protests during, testing during
studie d » studie 2, studie _, studie 1

• The words AND, OR and NOT may confuse the search; try adding quotes: "tests during studie d ((filosofia pela) OR (filosofia para)) literatura".
