The infinitive form ends in t (archaically, ti). It is the form found in dictionaries and the form that follows auxiliary verbs (for example, muzu te slyset"I can hear you"). Czech verbs have three grammatical moods: indicative, imperative and conditional. The imperative mood adds specific endings for each of three person (or number) categories: -/-i/-ej for second-person singular, -te/-ete/-ejte for second-person plural and -me/-eme/-ejme for first-person plural. The conditional mood is formed with a particle after the past-tense verb. This mood indicates possible events, expressed in English as "I would" or "I wish".
What are the grammatical moods of Czech verbs?
****
The answer: indicative, imperative and conditional

Archival descriptions of the permanent holdings of the federal government in the custody of NARA are stored in Archival Research Catalog (ARC). The archival descriptions include information on traditional paper holdings, electronic records, and artifacts. As of December 2012, the catalog consisted of about 10 billion logical data records describing 527,000 artifacts and encompassing 81% of NARA's records. There are also 922,000 digital copies of already digitized materials.
Archival descriptions include traditional paper holdings, electron records, and what?
****
The answer: artifacts

Chemical defense is another important defense found amongst species of Coleoptera and Lepidoptera, usually being advertised by bright colors, such as the Monarch butterfly. They obtain their toxicity by sequestering the chemicals from the plants they eat into their own tissues. Some Lepidoptera manufacture their own toxins. Predators that eat poisonous butterflies and moths may become sick and vomit violently, learning not to eat those types of species; this is actually the basis of Mullerian mimicry. A predator who has previously eaten a poisonous lepidopteran may avoid other species with similar markings in the future, thus saving many other species as well. Some ground beetles of the Carabidae family can spray chemicals from their abdomen with great accuracy, to repel predators.
Insects become toxic by doing what with the chemicals from plants?
****
The answer: sequestering

The problem: Answer a question about this article:
In most bacteria, a cell wall is present on the outside of the cell membrane. The cell membrane and cell wall comprise the cell envelope. A common bacterial cell wall material is peptidoglycan (called "murein" in older sources), which is made from polysaccharide chains cross-linked by peptides containing D-amino acids. Bacterial cell walls are different from the cell walls of plants and fungi, which are made of cellulose and chitin, respectively. The cell wall of bacteria is also distinct from that of Archaea, which do not contain peptidoglycan. The cell wall is essential to the survival of many bacteria, and the antibiotic penicillin is able to kill bacteria by inhibiting a step in the synthesis of peptidoglycan.
What composes the cell envelope?
****
The answer:
cell membrane and cell wall
