Explanation/Пояснение:
161. The correct answer is "not to sell" instead of "not selling". We use the infinitive form Не продавать to express that the old products have not been sold in recent years.
162. The correct answer is "to replace" instead of "to be replaced". The old products need to be replaced by the new ones, so we use the infinitive form Заменить.
163. The correct answer is "have been" instead of "are". "The last few months have been difficult" implies that the difficulty started in the past and continues until the present. Therefore, we use the present perfect tense Были.
164. The correct answer is "have been working" instead of "are working". This is because we are referring to the actions of the people in the research and development department during the last few months. We use the present perfect continuous tense Работали to show an action that started in the past and still continues.
165. The correct answer is "need" instead of "are needing". The people in the research and development department need a break in the present. We use the base form Нужен of the verb.
166. The correct answer is "had" instead of "have". This is because the sentence is in the second conditional form, expressing a hypothetical situation. If we had more money, we would employ more people. Therefore, we use the past simple form Было.
167. The correct answer is "would employ" instead of "employ". Following the same conditional structure as the previous answer, we use the conditional tense Наняли бы to express the hypothetical situation of employing more people.
168. The correct answer is "will be made" instead of "are made". The decisions about taking on more staff will happen in the future after careful and long consideration. Therefore, we use the future tense Будут приняты.
169. The correct answer is "feel" instead of "are feeling". The phrase "For the moment" indicates a temporary situation, so we use the simple present tense Чувствуем.
170. The correct answer is "are not" instead of "not to be". The last sentence is stating that currently, we are not in a financial position to hire more staff. We use the present simple tense Не находимся.
