Solvent solution (c) Dissolve 1.00 g of the solvent or solvents present in the substance to be examined in dimethyl sulphoxide R or water R, if appropriate, and dilute to 100.0 ml with water R. Dilute to give a concentration of 1/20 of the limit(s) stated in Table 1 or 2 (see 5.4. Residual solvents).

“if appropiate” seems to be used to describe “dimethyl sulphoxide R or water R”
There are 3 steps: (1) Dissolve 1.00 g of the solvent or solvents present in the substance to be examined in dimethyl sulphoxide R or water R, if appropriate (i.e. use dimethyl sulphoxide R or water R whichever is appropriate) and; (2) Dilute to 100.0 ml with water R; (3) Dilute to give a concentration of 1/20 of the limit(s) stated in Table 1 or 2 (see 5.4. Residual solvents). = = = = = =
好奇问句, 是不是准备100.0 ml水, 然后将含有solvent的水(或二甲基亚砜)滴进100.0ml水内, until the concentration is to be 1/20 of the limit(s) stated in Table 1 or 2 (see 5.4. Residual solvents).
第一层： Dissolve 1.00 g of the solvent or solvents in dimethyl sulphoxide R or water R, and dilute to 100.0 ml with water R.
第二层： Dissolve 1.00 g of the solvent or solvents present in the substance（蓝色部分用于修饰“solvents”，指通过质量研究，发现substance中存在一种或几种残留溶剂） in dimethyl sulphoxide R or water R, if appropriate, （蓝色部分作状语，用于修饰前面一整句，指应根据情况选择用二甲亚砜还是用水稀释。如果二甲亚砜本身就是待检测的残留溶剂，那当然不能再用二甲亚砜来稀释了）and dilute to 100.0 ml with water R.
第三层： Dissolve 1.00 g of the solvent or solvents present in the substance to be examined （紫色部分用于修饰“substance”，指这是需要检测的substance，即供试品）in dimethyl sulphoxide R or water R, if appropriate, and dilute to 100.0 ml with water R.
(1) Dissolve 1.00 g of {[(the solvent or solvents) present in the substance] to be examined} [(in dimethyl sulphoxide R or water R), if appropriate] and; (2) Dilute to 100.0 ml with water R; (3) Dilute to give a concentration of 1/20 of the limit(s) stated in Table 1 or 2 (see 5.4. Residual solvents)

英文名词有单众数之分。为了清楚, 故有XXX or XXXs, 或简化为XXX(s) 。有些法律文件为免太多“XXX or XXXs”, 会一律用singular, 但事先声明singular亦包含plural where appropriate.
