Here is a question about this article: The form of the verb varies with person (first, second and third), number (singular and plural), tense (present and past), and mood (indicative, subjunctive and imperative). Old English also sometimes uses compound constructions to express other verbal aspects, the future and the passive voice; in these we see the beginnings of the compound tenses of Modern English. Old English verbs include strong verbs, which form the past tense by altering the root vowel, and weak verbs, which use a suffix such as -de. As in Modern English, and peculiar to the Germanic languages, the verbs formed two great classes: weak (regular), and strong (irregular). Like today, Old English had fewer strong verbs, and many of these have over time decayed into weak forms. Then, as now, dental suffixes indicated the past tense of the weak verbs, as in work and worked.
What is the answer to this question: How did Old English strong verbs express the past tense?
****
So... altering the root vowel

Here is a question about this article: Model plants such as Arabidopsis thaliana are used for studying the molecular biology of plant cells and the chloroplast. Ideally, these organisms have small genomes that are well known or completely sequenced, small stature and short generation times. Corn has been used to study mechanisms of photosynthesis and phloem loading of sugar in C4 plants. The single celled green alga Chlamydomonas reinhardtii, while not an embryophyte itself, contains a green-pigmented chloroplast related to that of land plants, making it useful for study. A red alga Cyanidioschyzon merolae has also been used to study some basic chloroplast functions. Spinach, peas, soybeans and a moss Physcomitrella patens are commonly used to study plant cell biology.
What is the answer to this question: What common plant has been used for studying the production of sugar?
****
So... Corn

Here is a question about this article: Saint Helena was first settled by the English in 1659, and the island has a population of about 4,250 inhabitants, mainly descended from people from Britain settlers ("planters") and soldiers and slaves who were brought there from the beginning of settlement initially from Africa (the Cape Verde Islands, Gold Coast and west coast of Africa are mentioned in early records), then India and Madagascar. Eventually the planters felt there were too many slaves and no more were imported after 1792.
What is the answer to this question: When was Saint Helena first settled?

So...
1659
